2 Introduction
masibus MTS200 mas TER T-Sync has been developed for the time synchronization requirements
in various industries like power, process, IT, telecommunications. Masibus next-generation GPS clock
provides enhanced performance and security. It is the most featured and cost-effective GPS time
synchronization solution available in 1U compact size. MTS200 is Reliable and provides time accuracy of
150nsec at basic level.
To begin with, masTER T-Sync model MTS200 offers precise timing accuracy using GPS satellites; it
generates accurate output pulses and time codes in multiple formats. It‟s necessary every time to Lock
GPS once after power ON in order to ensure the better accuracy.
masTER T-Sync Model MTS200 synchronizes a wide variety of microprocessor-based power system
equipment including: SCADA systems, remote terminal units (RTUs), protection relays, sequence of
event recorders, digital fault recorders, tariff meters, Slave Display Units, Data Loggers and other
Intelligent Electronic Devices (IEDs). Being a Field programmable device using HyperTerminal / Putty, a
very common application in Windows or 8 key Keypad provided on the front panel, masTER T-Sync Model
MTS200 allows the user to alter the settings or choose from Time codes. Each output can feed directly to
different areas through electrically isolated ports which ensure reliable operation in a harsh substation
environment.
masTER T-Sync Model MTS200 generates a wide range of timing signals via seven output ports.
Standard configurations of masTER T-Sync Model MTS200 is equipped with two serial ports, a 1PPS
Port, 1 IRIG-B TTL / IEEE 1344 (field configurable)and three PFC relay outputs for POWER,
WATCHDOG, GPS LOST alarm and standard PMOS relay based pulse output of PPM/PPH or RTC ON
event.
masTER T-Sync Model MTS200 is available with optional feature outputs such as additional 1Gbps eth1
port, 4 additional PMOS relay based pulse outputs each configurable from a second to a day period time,
two IRIG-B127 / IEEE 1344/C37.118-2005 Amplitude modulated output (field configurable) or 1 IRIG TTL
+ 1 IRIG-AM (field configurable) output. Com1 Serial port provides NMEA-GPRMC format. Com2 serial
port is configurable for either NGTS or T-format or GPZDA or GPGGA.
MTS200 is a full featured NTP Server (NTPv2/v3/v4) with all available NTP authentication methods
available. MTS200 provides time synchronization to different network Clients which are supporting NTP
protocols. In addition NTP unicast, MTS200 can be configured with broadcast or multicast mode.
masTER T-Sync Model MTS200 units feature a front panel display, giving both installation teams and
users visual feedback about the time data being generated on the outputs. LED indicators provide “at a
glance” status information. It also hosts various protocols such as Telnet, SSH, HTTP, HTTPS, SNMP for
its own monitoring and configuration management. MTS200 is capable to log alarms internally as well as
on remote server through syslog protocol and generate various alarms over syslog and SNMP traps.
The optimized Receiver/Antenna system employed in masTER T-Sync Model MTS200 provides time
information from the GPS satellite constellation. Dynamic T-RAIM processing is used to eliminate any
aberrant satellite signals from the timing solution. The result is timing precision on all outputs with
accuracy similar to that normally seen only in laboratory instruments.
masTER T-Sync Model MTS200 unit is Rack Mount and its mechanical dimensions are 482.6(W) x 44(H)
x 241(D) mm (IP 20 Enclosure).It is supplied complete with all hardware and software required for the
installation, including the Antenna, Antenna mounting kit, 10 meters Antenna cable, 3 meters RS-232
cable and 10 meters RG58 Co-axial cable. (Depends upon commercial terms & condition)

3 GPS Fundamentals
mas TER T-Sync Model MTS200 device is a GPS/GNSS based receiver clock device which provides
accurate time output with 1PPS signal. Satellite Navigation system is a system of satellites that provide
autonomous geo-spatial positioning with global coverage. It allows small electronic receivers to determine
their location (longitude, latitude, and altitude) to high precision (within a few meters) using time
signals transmitted along a line of sight by radio from satellites. GNSS is a satellite navigation system that
is used multiple navigation systems mainly GPS and GLONASS. GNSS also include satellite navigation
systems of SBAS, QZSS, Galileo systems etc.
GPS satellite navigation system is maintained by United States of America since 1994 which consists of
at-least 24 operational satellites out of 32 satellites in six orbital planes orbiting at an altitude of
approximately 20,200 km. In typical GPS operation, four or more satellites must be visible to obtain an
accurate result. Satellite-based navigation systems use a version of triangulation to locate the user,
through calculations involving information from a number of satellites.
Figure 3-1 The Basis of GPS
If one considers Figure 1 which shows a flat plane. X and Y are two known fixed points on the plane. P is
an unknown point. If the distances PX and PY can be measured, then the position of point P can be
calculated. Actually there is an ambiguity in that point P‟ would also fit the measurements. This can be
resolved if the position of a third fixed point Z is known since PZ is different to P‟Z. This can be summed
up by saying that the unknown point P lies at the intersection of three circles based on the known points
X, Y and Z.
When the plane becomes three dimensional spaces, the circles become spheres. The intersection of two
sphere is a circle, and the intersection of three spheres is a pair of points analogous to the points P and
P‟ of the flat plane case. As for the flat plane case a measurement from an extra fixed point is required to
absolutely resolve the ambiguity, although in many cases the ambiguous point would be below the
surface of the world. Thus to achieve the objective, GPS must provide accurate measurement of distance
from the unknown location of the receiver to 4 known points.
GLONASS based satellite navigation system is maintained by Russia, a fully functional navigation
constellation in 1995. After the collapse of the Soviet Union, it fell into disrepair, leading to gaps in
coverage and only partial availability. It was recovered and fully restored in 2011. It provides an
alternative to Global Positioning System (GPS) and is the second alternative navigational system in
operation with global coverage and of comparable precision.
A fully operational GLONASS constellation consists of 24 satellites, with 21 used for transmitting signals
and three for in-orbit spares, deployed in three orbital planes. The three orbital planes' ascending nodes
are separated by 120° with each plane containing eight equally spaced satellites. The orbits are roughly

Model: MTS200 (1U)

Issue no. : 03
User’s Manual Page 12 of 195 Page 12 of 195
circular, with an inclination of about 64.8°, and orbit the Earth at an altitude of 19,100 km, which yields an
orbital period of approximately 11 hours, 15 minutes. The overall arrangement is such that, if the
constellation is fully populated, a minimum of 5 satellites are in view from any given point at any given
time. This guarantees for continuous and global navigation for users world-wide.
A characteristic of the GLONASS constellation is that any given satellite only passes over the exact same
spot on the Earth every eighth sidereal day (1 sidereal day = 23 hours, 56 minutes, 4.0916 seconds).
However, as each orbit plane contains eight satellites, a satellite will pass the same place every sidereal
day. For comparison, each GPS satellite passes over the same spot once every sidereal day. So
opposed to the GPS the ground-track of the GLONASS satellites do not repeat after one day. This avoids
the resonance effects which makes station keeping of GPS satellites difficult and expensive.
In GPS navigation system, all satellites operates at same frequency at 1.57542 GHz (as L1 signal) and
1.2276 GHz (as L2 signal) using CDMA technique whereas GLONASS navigation system, all satellites
operate on different frequencies using originally a 25-channel frequency FDMA technique spanning from
1602.5625 MHz to 1615.5 MHz, known as the L1 band.
As GNSS uses navigation satellite system of GPS, GLONASS and other available systems in space,
GNSS receivers can easily observer 10 to 12 satellites at a time. As more number of satellites are visible,
more accuracy in receivers output signals are achieved.
Each visible satellite broadcast two types of information in its message format i.e. Almanac and
Ephemeris. Almanac data is course orbital parameters for all visible satellites. Each visible satellite
broadcasts Almanac data for allvisible satellites. This Almanacdata is not very precise and is considered
valid for up to several months. Ephemeris data by comparison is very precise orbital and clock correction
for each visible satellite and is necessary for precise positioning. Each visible satellite broadcasts only its
own Ephemeris data. The ephemeris is updated every 2 hours and is usually valid for 4 hours.
