INTRODUCTION 1
This chapter provides an overview of the JNSGyro-2T, including its features
and physical elements. In addition, a brief description of the principals of GPS
operation is presented.
Overview
JNSGyro-2T (Figure 1-1) is a dual frequency satellite based two-antenna
system that measures true heading. It contains two 20-channel geodetic quality
dual frequency GPS/GLONASS receivers packaged in one small box that is
connected to two antennas whose base-line is fixed at the time of installation.
Figure 1-1. JNSGyro-2T
The JNSGyro-2T can receive and process L1 and L2 signal. The GNSS
component of JNSGyro-2T means you can access both the GPS (Global
Positioning System) satellites of the United States, and the GLONASS (Global
Navigation Satellite System) satellites of the Russian Federation, increasing the
number of satellites your board can detect, thus improving the accuracy of your
measuring points, increasing productivity, and reducing cost.

Principles of Operation
The measuring with the right GPS board can provide users accurate and precise
positioning, a requirement for any measuring project.
This section gives an overview of GPS and board functions to help you
understand and apply GPS principles, allowing you to get the most out of your
board.
GPS Overview
The Global Positioning System (GPS) is a satellite-based, line-of-sight
radio navigation system run by the United States Department of Defense
(DoD). This system offers a global, all weather, 24-hour positioning, veloc-
ity, and time service to any user equipped with a GPS tracking receiver,
who is on or near the Earth’s surface. The Global Navigation Satellite Sys-
tem (GLONASS) is the Russian Federation Ministry of Defense counterpart
to GPS. At any one time, with a standard 15-degree angle, up to 10 or 12
GPS satellites are visible from any point on earth. When a board can also
track GLONASS satellites, between 10 and 16 satellites are visible.
For information on the status of the GPS constellation, visit
http://tycho.usno.navy.mil/ or http://www.navcen.uscg.gov/.
For GLONASS, visit http://www.glonass-center.ru/frame.html.
Despite numerous technical differences in the implementation of these sys-
tems, both GPS and GLONASS have three essential components:
• Space – GPS and GLONASS satellites orbiting approximately 12,000
nautical miles above Earth and are equipped with a clock and radio.
These satellites broadcast digital information (ephemerides, almanacs,
time frequency corrections, etc.).
• Control – Ground stations located around the Earth that monitor the sat-
ellites and upload data, including clock corrections and new ephemeri-
des (satellite positions as a function of time), to ensure the satellites
transmit data properly.
• User – The community and military that use GPS/GLONASS receivers
and the corresponding satellites to calculate positions.

INTRODUCTION
Principles of Operation
Calculating Positions
Once the receiver locks on to a satellite, it starts recording measurements
and receiving various digital information (ephemeris, almanac, and so on)
the satellites broadcast. To calculate a position, receivers use the following
formula:
Velocity x Time = Distance
Where Velocity is the speed at which radio waves travel (i.e., the speed of
light) and Time is the difference between the signal transmission time and
signal reception time.
To calculate absolute 3-D positions – latitude, longitude, altitude – the
receiver must lock on to four satellites. In a mixed, GPS and GLONASS
scenario, receiver must lock onto at least five satellites to obtain an absolute
position.
To provide fault tolerance using only GPS or only GLONASS, the receiver
must lock onto a fifth satellite. Six satellites will provide fault tolerance in
mixed scenarios. Usually, the number of GPS and GLONASS satellites in
view does not exceed twenty (20).
Once locked on to a satellite, the receiver collects ephemerides and alma-
nacs, saving this information to its NVRAM (Non-Volatile RAM).
• GPS and GLONASS satellites broadcast ephemeris data cyclically, with
a period of 30 seconds.
• GPS satellites broadcast almanac data cyclically with a period of 12.5
minutes; GLONASS satellites broadcast almanac data cyclically with a
period of 2.5 minutes.
GPS Positioning
Achieving quality position results requires the following three elements:
• Accuracy – The accuracy of a position depends upon the number, signal
integrity, and placement (also known as Dilution of Precision, or DOP)
of satellites.
–Differential GPS (DGPS) strongly mitigates atmospheric and orbital
errors.
–The more satellites in view, the stronger the signal, the lower the DOP
number, providing more accurate positioning.
• Availability – The availability of satellites affects the calculation of
valid positions. The more visible satellites available, the more valid and

INTRODUCTION
Principles of Operation
1
accurate the position. Natural and man-made objects can block, inter-
rupt, and weaken signals, lowering the number of available satellites.
• Integrity – Fault tolerance allows a position to have greater integrity,
increasing accuracy. Several factors combine to provide fault tolerance,
including:
–Receiver Autonomous Integrity Monitoring (RAIM) detects faulty
GPS and GLONASS satellites and removes them from the position
calculation.
–Wide Area Augmentation System (WAAS) and European
Geostationary Navigation Overlay Service (EGNOS) creates and
transmits DGPS correction messages.
–Five or more visible satellites for only GPS or only GLONASS; six or
more satellites for mixed scenarios.
–Current ephemerides and almanacs.
–Several algorithms to detect and correct faulty information.
Conclusion
GNSS users can use JNS GNSS receivers to collect data from a network of
satellites and control stations to triangulate precise points anywhere on
Earth.
This overview simply outlines the basics of GPS and GLONASS position-
ing. For detailed information, visit the JNS website

INTRODUCTION
JNSGyro-2T Overview
JNSGyro-2T Overview
The system JNSGyro-2T is based on GNSS receivers. When power is turned on
the JNSGyro-2T’s two 20 channels receivers initialize and begin tracking
visible GPS satellites. Each of the JNSGyro-2T boards’ channels can be used to
track P-L1, or P-L2 and Carrier signals. The number of channels available
allows the system to track all visible satellites at any time and location.
Once the signal is locked in the channel, it is demodulated and necessary signal
parameters (carrier and code phases) are measured. In addition, broadcast
navigation data are retrieved from the navigation frame.
After the JNSGyro-2T boards lock on to four or more satellites, it is possible to
solve the so-called “absolute positioning problem” and compute the JNSGyro-
2T boards’ coordinates (in WGS-84 or another datum) and time. All this
information can be downloaded through the appropriate port onto a computer
and processed when needed.
JNSGyro-2T can also operate in the RTK or DGPS modes receiving differential
corrections from an external base station to provide differentially corrected
position and velocity.
