 Unit does not power up

(No LED light) Check 12V and Ground connection at monitor.

Disconnect the unit from the monitor and visually inspect the

connector pins and cable for damage.

If using a Raven monitor, ensure that the BLUE power wire is

connected to a fused-switched 12V source.

 Status LED does not go

GREEN after 15 minutes Check that there are no obstructions for clear view of satellites

on all sides of the SkyTrak. (i.e. Buildings, Metal Sheds, etc.)

Disconnect unit from monitor, wait 5 seconds and reconnect.

After reconnection, watch the Status LED.

 If the LED flashes RED—GREEN—RED, the

microprocessor is working properly and the problem lies

within the GPS module; please contact Squibb-Taylor.

 If the LED does not flash, the problem lies within the

circuitry of the unit; please contact Squibb-Taylor.

Troubleshooting

Problem Possible Remedy

 Status Led is GREEN, but no

9 Hertz GPS Velocity Sensors March 2014 Form IOM-SK2-1009, Rev.02

GPS VELOCITY SENSOR

SkyTrak is a GPS based velocity sensor that

produces true ground speed pulses to equipment

designed to interface with radar ground speed and

wheel speed sensors. SkyTrak can be quickly

transferred from vehicle to vehicle, provides high

accuracy, and is easy to install and use. Simply

make the connection to your monitor/control

equipment, perform the same calibration you would

use for other pulse sensors, and you’re ready to go.

Standard Features

 9 updates per second provides high

precision velocity readings

 Completely self-contained (GPS,

antenna, and velocity-to-pulse

converter)

 50 Channel GPS receiver features

high acquisition and tracking

sensitivity

 Selectable output pulse rates ensures

monitor compatibility

 0.1 MPH accuracy from 0.5 to 50

MPH

 UV stable, polycarbonate enclosure

 Magnet mount simplifies installation

 Diagnostic LED’s built into the cable

help to quickly verify performance

 Consistent pulses/foot output unit to

unit

Mounting Considerations

 The SkyTrak mounting location should have a clear view of satellites on all sides.

 The SkyTrak unit must be mounted with the dome pointing to the sky.

 Avoid overhead metal structures that can block the satellite signals.

 Avoid mounting in areas with excessive vibration. An antenna that moves or sways may

produce ground speed errors. The idea is to have the antenna move only when the vehicle is

moving for accurate true ground speed measurement.

 To protect against dirt and debris entering the interior of the unit, avoid mounting in locations

close to the ground.

 Make sure the cable can be safely routed to the connection point.

 SkyTrak can be mounted on a flat surface such as the roof of the vehicle cab.

 Position the SkyTrak status indicator so that it is easily viewable.

Power Supply Warnings:

DICKEY-john®

A DICKEY-john®unit cannot be used in Raven applications by using a pin-for-pin adapter.

Many Raven devices do not supply adequate power to operate the SkyTrak directly. Therefore,

a Raven specific connector must be supplied which provides for connection of an independent

12 volt power source to the SkyTrak. The SkyTrak model SK2-1009-R provides the necessary

power connection for Raven applications.

It is also very important that a good ground is provided through the connector.

Raven

SkyTrak requires 4.8 to 16 volts at about 0.1 amps to operate. Although the Raven controller

speed sensor interface connector provides 5 volts and ground to power some radar guns, it does

not supply enough power for the SkyTrak sensor. SkyTrak power must be supplied

separately. The positive lead of the SkyTrak power should be connected to the blue lead at the

connector end of the SkyTrak harness. To simplify installation, a 1-pin crimp-on connector is

provided. Using the connector will also make it easy to unplug the SkyTrak if it needs to be

removed. Ground, or the power (-) connection, is provided through the controller's speed sensor

interface connector which must be a proper ground. Choose a power source that is fused and

switches off when the tractor is off.

Calibration

After installing SkyTrak, your control equipment will need to be calibrated. Follow the calibration

procedure for your controller or monitor as if you were using a radar or wheel speed sensor. Typi-

cally, this involves driving an accurately measured distance to determine a speed cal value for your

system.

Before running the calibration, allow the SkyTrak to download a full satellite table by turning on

SkyTrak where it has a clear view of the sky for about ten minutes. The status indicator should be

solid green (using 4 or more satellites) before performing the calibration.

Pulse Output Rate

The pulse rate for the SkyTrak is factory set to 58.94 PPS (pulses per second) / MPH (mile per

hour). This setting will be suitable for most applications. If your application requires a different rate,

a small jumper under the SkyTrak cover allows the pulse output rate to be changed.

Available rates are...

Position 1 58.94 PPS/MPH — 40.1864 pulses/foot

(Factory setting for most models)

Position 2 44.21 PPS/MPH — 30.1432 pulses/foot

Position 3 Reserved

Position 4 Reserved

Position 5 9.823 PPS/MPH — 6.6975 pulses/foot

(Factory setting for Micro-Trak®)

The 58.94 PPS/MPH setting is shown here, with the jumper installed horizontally for Position 1.

(Position 1 is the same as having no jumper installed.) For Positions 2, 3, 4, & 5, the jumper must

be installed vertically, in line with the corresponding Position Number. For example, for 9.823

PPS/MPH, install the jumper vertically, over the two pins in line with the number 5.

Status LED Operation

 The SkyTrak power indicator will be on GREEN as long as power is applied to the unit.

 When power is first applied, the SkyTrak status LED will FLASH RED-GREEN-RED (when jump-

er is in position 1, 58.94 PPS/MPH) to indicate the pulse output jumper position. For example, if

the jumper is in position 5, (to achieve the 9.823 PPS/MPH rate), the status LED will FLASH RED

-GREEN-RED five times.

 While the SkyTrak GPS receiver is building the GPS satellite table, the status LED will be RED.

The startup time depends on how long the unit has been off but is less than 1 minute.

 When the GPS is ready, the status LED will go from RED to GREEN when sitting still (not in mo-

tion). When in motion, the status LED will flash between RED and GREEN giving an ORANGE

appearance.

 If the GPS loses or never acquires the satellite signal, the status LED will be solid RED (when

moving or in the idle position) until a good signal is re-acquired.

 If the GPS is healthy and in idle, the status LED will be GREEN.
