1.1 TECHNICAL DESCRIPTION
The 1.2M VSAT Antenna System is an elevation over azimuth positioner featuring the simple, rugged Roto-Lok
drive system for the azimuth which produces very low backlash, high stiffness and high reliability and driven by a
low backlash, gear box with a DC motor. The elevation system features a highly reliable linear actuator to control
elevation. All drive components are high strength steel, housed in lubricated for life housings which results in the
most reliable, no maintenance system with the minimum of weight. The reflector is a offset, prime focus, aluminum
illuminated by a corrugated horn. The RF power amplifier may be installed on the feed boom, or inside the truck. A
Handcrank across AZ axis is included allowing easy antenna positioning if the controller malfunction and elevation
actuator my be driven with a battery charger or other 12 volt system. The basic 2-port antenna system weighs
only 150 pounds.
RF SYSTEMS
The offset reflector/feed system produces co-polarization patterns that easily meet the 29-25 log theta requirement.
The .8 f/d optics reduces off axis cross-pol in the asymmetrical plane. The RF power amplifier may be installed on
the feed boom, or inside the truck. Waveguide that run to power amp across each axis can be via twist-flex or
rotary joints. The system can be configured for either 2-port or 4-port
The patented Roto-Lok drive system utilizes highly reliable aircraft control cables in a redundant configuration to
achieve a zero backlash, light weight, very stiff drive system. It achieves this high tech performance using low
tech components by simply wrapping the cable around the driver capstan several times before wrapping the larger
driven drum. The method used to wrap the capstan results a minimum free length of cable. The load in the cable
on the main drum is exponentially reduced as it is wrapped around the drum. Therefore the total elongation of the
cable when under load is minimized. The Roto-Lok system results in stiffness of up to 10 times that of comparable
gear or harmonic drive systems. The cables are pretensioned and spring loaded at the main drum attachment
point which eliminates backlash at installation and from any unexpected cable stretch in the future.
ROTO-LOK DRIVE SYSTEM
The Az Roto-Lok drive system is driven by a low backlash worm gear set with a 40:1 ratio. The factory low back
lash of the worm gear set is reduced further by the Roto-Lok drive ratio resulting in a lash equivalent to only .06 dB
as seen by the RF system. The gear sets are housed in a sealed housing which allows the gear set to be
continuously lubricated in synthetic oil which maximizes gear efficiency and minimizes wear.
SECONDARY DRIVE SYSTEM
Light weight, reliable, servo quality DC motor with integral gear box is used for the Az drive. This motor was
selected because it provides the best torque to weight ratio as well as allowing dual speed operation for slewing
and peaking. These motors produce constant torque over the speed range with no cogging at low speeds which
ensures smooth operation when peaking the antenna. The 24V DC design provides current limiting torque control
and will allow vehicle battery operation if necessary. A linear actuator is used in the elevation drive, a low cost
alternative to a typical roto-lok system. This system offers dependable and continuous constant torque over the full
travel motion of the elevation axis.
MOTOR DRIVES
SECTION1- OVERVIEW

5
The system will interface with a jog controller which allows remote control of the system. Each axis position is
displayed as well as limit indications. The unit will also interface with a full function controller with features such as
automatic stow, GPS/flux-gate input and automatic satellite pointing and tracking.
CONTROLS
Except for the drive components and bearings, the AZ/EL base plate, AZ/EL casting, feedboom and backing
structure and covers will be all aluminum. The fabrication of parts and assembly will be of world wide quality
standards.
CONSTRUCTION
SECTION 2- INSTALLATION AND SET-UP
The 1.2M VSAT positioner has been fully tested with the controller prior to shipment. All position feedback, limit
sensing, limit switches (except elevation stow) and motor speeds have been calibrated or set. The positioner
should be secured to the vehicle, connecting wave guide or boom mounted HPA cables, connecting coax,
connecting control cables to controller and connecting auxiliary control cable to wave guide switch if applicable.
The vehicle roof should be reinforced with a substructure capable of carrying the wind loads as specified on the
interface drawing to the vehicle frame. The structure should be stiff enough to prevent no more than a 0.5 dB of TX
gain loss in a 30mph gusting to 45mph wind. (850 IN/LB moment @ .25º)
A 3-inch diameter hole should be in the mounting surface. The mounting surface must be flat within .005 inch to
prevent binding the azimuth bearing after torquing the mounting bolts. No obstruction should be above the interface
surface in a 17-inch diameter envelope. Any other roof-mounted equipment such as air conditioners should be
more than 64 inches from center of interface bolt pattern. A hard flat surface is required for the feed bumpers as
shown on the interface drawing.
2.1 GENERAL

2.5 CONTROLLER/POSITIONERVERIFICATION TEST CONT.
Watch reflector surface approach feed horn.
Press STOP when reflector is within 2” of feed horn.
Jog down until reflector presses on rubber padding on feed housing.
Adjust stow limit switch if necessary by bending lever. Stow switch is on east side with long lever. (East is the left
side as viewed from behind the reflector)
2.6 FINAL CALIBRATION OF SYSTEM
Check AZ ZERO position on roof. If azimuth controller will stow at AZ = 0.0 degrees you may adjust AZ zero
voltage +/- 2º to bias stow position. Adjust zero voltage per Section 4.1.1 of controller manual.
SECTION 3- AZIMUTH POSITIONING SYSTEM
The azimuth bearings are precision ground sealed bearings with a dynamic and static moment capacity of over
four times the worst-case wind load specification. They are located on the AZ/EL casting top and bottom. The
bearing is packed with synthetic grease during assembly and no further greasing is required.
Because of the excess capacity, low rpm, and low number of cycles, no maintenance is required.
3.1 AZIMUTH BEARING
3.2 AZIMUTH GEARBOX
The azimuth gearbox is a low backlash worm gear box. The worm gear drive isolates any backlash in the motor
drive from the system. In addition, since it is a 40:1 ratio it will not back drive, eliminating any need for a brake on
the drive train. (See Fig.)
The motor drives the input worm via a quill/female
hole and square key. The worm shaft is extended
with a hex shape installed for the hand crank. The
azimuth capstan is secured to the output shaft with a
square key knurl plus permanent locktite to eliminate
any backlash between the capstan and gearbox.
The low backlash is achieved by selective fit of the
worm and worm gear. The nominal backlash for the
gearbox is 30’ which is reduced by the Roto-Lok
drive to less than 4’of the beam of the antenna. The
gearbox contains synthetic oil filled half way to the
level plugs. Because of the design capacity of the
gearbox, low rpm and limited cycles experienced by
an SNG system, no maintenance is required.

8
3.3 AZIMUTHMOTOR
The azimuth drive motor is a 24 DC motor with integral 30:1 spur gear train. (See fig on pg.6) The motor armature
rotates at up to 3000 rpm causing a high frequency noise that will vary depending of the loading condition of the
motor.
The maximum output speed is 100 rpm. The output shaft is “D” shaped with a special adapter with a slot for a
square key.
Since the low backlash worm gear drive isolates the backlash from the motor, any backlash between the shaft
adapter, square key or motor gear train will not be seen by the reflector bore sight. The motor is mounted to an
adapter plate that is bolted to the gearbox with (4) screws.
No maintenance of the azimuth motor is required.
The patented azimuth Roto-Lok drive produces a zero backlash; high stiffness, no wear, no lubrication, and
maximum reliability drive system. The system consists of two 1/16, 7x19 stainless steel aircraft control cables
reverse wrapped twice around the grooved capstan and once around the drum, with solid connections on one end
and high force Belleville springs on the other end (Fig. Below). One cable has the capacity to withstand a 75mph
wind load. The additional cable is used to provided increased stiffness and drive redundancy. If a cable becomes
damaged during usage, cut off cable and continue to use positioner. Replace cable when time permits
at your maintenance facility.
The cables are sized to last the life of the positioner. The springs will automatically compensate for any elongation
of the cable.
Cable position should be checked as per the periodic maintenance schedule in Section 6. If cables have drifted,
manually move cables using blunt instrument on the azimuth drum until the correct position is obtained.
At installation the Belleville springs are collapsed until no “air” is seen between the springs. You should check this
condition yearly to account for the slow settling of the cable strands. Use pliers to hold stud and 1/4 box end
wrench to tighten nut. Be sure not to over tighten. Tighten until springs are almost fully collapsed. (Fig
below)
3.4 AZIMUTHROTO-LOK CABLE DRIVE

9
3.5 AZIMUTH POSITION FEEDBACK
The azimuth position feedback is produced by a 10 turn, 1K-ohm potentiometer driven by a gear located on
kingpin post . (Fig. Below) Since the Roto-Lok drive has no backlash, the position feedback is as accurate (1%)
as the resolution (.3°) and accuracy of the potentiometer and the backlash between the potentiometer and the
azimuth capstan. The potentiometer is sealed and rated for IP 65 environment - wind, rain, dust, etc.
The potentiometer is mounted on AZ/EL casting. The azimuth potentiometer is slotted and driven by a belt and a
small sprocket located on the AZ king pin and the small gear on the potentiometer. The potentiometer is mechani-
cally centered at the travel position (5 turns from either end) when AZ platform is in the AZ stow position. This is
accomplished by removing the belt from the potentiometer gear. The potentiometer may also be electrically
zeroed by the controller. See pertaining section of the controller manual.
3.6 AZIMUTH STOW AND LIMIT SWITCHES
The controller uses the AZ potentiometer voltage to determine limits. Therefore, the positioner is equipped with
only an azimuth stow position switch.
The azimuth stow limit switch is mounted on the AZ/EL casting, on a boss next to azimuth drive sprocket. ( Fig.
Below) The switch is fixed relative to the mounting surface and is actuated by a small shoulder bolt located on the
azimuth potentiometer drive sprocket. The stow switch actuation occurs at slightly different positions depending if
you approach the stow position from CW or CCW. Therefore, the azimuth stow position will vary approximately 1º
from stowing from CW or CCW.
Since the controller drives to 0° AZ after sensing
the stow switch, the AZ stow position can be varied
by either changing the zero position of the AZ
potentiometer or zero voltage of the controller.

120MVSAT (With 360° AZ) (4 Overlapping +/- 95° Sectors)
Notes:
1) The Limits should be set after the potentiometer has been centered as described above. If the potentiometer is
moved from this position, the limits should be reset.
2) The AZ angle displayed by the controller is affected by several parameters in the controller. (These include AZ
Scale Factor, AZ Reference Position).
3) While setting the limits, watch the AZ capstan to make sure it does not run into the end of the cables.
4) The angles at the limits in the chart shown above are for nominal values of these parameters, and the values
actually displayed by the controller at the limits may vary.
4.1 ELEVATIONPIVOT ASSEMBLY
The elevation pivot assembly consists of a linear actuator assembly that
pivots between the two blades on the AZ/EL casting at the motor end
and pinned at backing plate clevis. The backing structure tubes pivot at
az/el base pivot blocks. All moving or pivoting points pivot in bronze
bushings or High tech polymer bushings. (See fig.) No maintenance is
required. If squeaking noise is heard, spray silicone lubricant with
“straw” nozzle down between the two pivot points.
4.2 ELEVATIONLINEARACTUATOR
The elevation actuator is a ball screw mechanism driven by a 12 volt motor
and integrated gearbox attached at the bottom of the actuator. The ball screw
offers high resolution and accurate repeatability, is designed to isolate
backlash in the drive from the system.
Because of the design capacity of the actuator, lifetime lubrication and limited
cycles experienced by an MVSAT system, no maintenance is required. (See fig.)
SECTION 4- ELEVATION POSITIONING SYSTEM

11
4.3 ELEVATION POSITION FEEDBACK
The elevation position feedback is produced by an electronic inclinometer located in the feed box. (See fig below)
No adjustment or maintenance is required. The inclinometer is electronically zeroed in the controller. See Section
2.3 in the controller Manual.
4.4 ELEVATION STOW AND LIMIT SWITCHES
The elevation stow switch is mounted in the Pol cover. The limit
switches are mounted in the elevation actuator gearbox.
The elevation up and stow switch do not require adjustment.
SECTION 5- FEED AND POLARIZATION POSITIONING SYSTEM
5.1 GENERAL
The Feed assembly consists of feed boom, upper and lower feed brackets, feed housing, RF components and
polarization drive housing. The feed boom is pivoted about the elevation axis to eliminate additional flex-guide
required if pivoted at edge of reflector. The pivot connection at the end of the feed arms in the upper feed bracket
is with brass bushings. A piece of 18” flex waveguide is used at the end of the waveguide tube to the OMT. The
feed/OMT is rotated by chain drive assembly and 12 VDC motor. Position feedback is from a 10 turn potentiom-
eter.
5.2 FEED
The feed assembly consists of an inclinometer, feed horn and OMT with male pivot bushings. The male bushings
pivot in delrin female bushings at each end of the OMT. The Bushings are mounted to a mounting plate. The pol
drive sprocket attaches to the OMT and the waveguide attaches to the other end with M6 screws at the rear
flange of the OMT. The feed/polarization drive is mounted underneath the pol mounting plate in the feed box with
the gear on the outside and the driving pol sprocket to rotate feed.
5.3 POLARIZATION DRIVE
The feed/polarization drive is mounted underneath the pol mounting plate in the pol drive box with a drive
sprocket mating to the motor shaft, which extends through the feed drive box. The polarization drive motor (See
fig on page 11) is a 12 VDC gear motor. Small gear is attached to the end of motor shaft which drives the small
gear to drive the position potentiometer. The controller travel limits are +/- 90 degrees for a 2-port. (See RCI
3050 Controller Manual section 3.3).

12
Since the low backlash chain drive isolates the feed from the motor, no brake is
required. No maintenance of the Polarization motor/assembly is required. The
polarization drive can be replaced only by a complete unit including the motor,
motor sprocket /gear, chain, elevation inclinometer, potentiometer and gear, and
drive sprocket.
5.5 POLARIZATION LIMITS
The controller uses the polarization potentiometer voltage to determine limits. The controller drives to 0 degrees
pol when it stows. The positioner has the mechanical capability of +/- 90 degrees per section 3.3 of the controller
manual. If the controller fails to terminate power to the motor and the system is driven to a hard limit stop, the DC
motor will stall. To correct, reset pol jam error in the controller.
5.6 FEED ASSEMBLY
The feed assembly consists of the feed, the polarization drive and the polarization potentiometer. The feed
assembly is installed as a complete unit and secured to lower feed bracket. The feed horn is mechanically
positioned with a template within 1/8” of the theoretical focal point of the reflector. This positioning assures the RF
System the gain and FCC compliance as stated in the specifications. Minor RF improvement can be realized by
optimizing the feed positioning using transmit or receive patterns. Inclinometer is mounted on the inside of feed
box.
5.4 POLARIZATION POSITION POTENIOMETER
The polarization feedback is produced by a 10 turn, 1K-ohm potentiometer driven by the motor gear, and
mounted in the feed box and shaft extends outside the box. The resolution and accuracy is 0.3 degrees. The
potentiometer is rated for IP 65 environment, Wind, Rain, and Dust etc… The potentiometer is mechanically set at
the one-half travel position, (5 turns from either end) and will read approximately 500 ohms at 0 degrees pol
(stow). The potentiometer may be set using the controller. The voltage reading at pol stow will read 2.5V at 0
degrees. See RCI controller manual Sec. 3.3

SECTION 6 - MAINTENANCE
6.1GENERAL
The 1.2 meter Mobile VSAT is designed such that any wear should never degrade performance below specifica-
tions and essentially no maintenance will ever be required. However, since it is impossible to ascertain or test for all
possible environments, the following check up is recommended each year. If any problems are observed, refer to
the appropriate section.
6.2ANNUALINSPECTION
AZIMUTH
1. Hand crank in azimuth, the unit should hand crank easily.
2. Check for unusual noise in azimuth bearing and azimuth gearbox.
