RSR GNSS Transcoder™ User Manual
Introduction
1.1 Overview
The Jackson Labs RSR GNSS Transcoder™ is a miniature, fully self-contained, real-time,
full-constellation, 10-channel GPS simulator. It can be used as an independent GPS L1 RF source
just like any other industry-standard GPS simulator, or be connected to an external
Position/Velocity/Navigation/Time (PVT/PNT) source to transcode the baseband NMEA PVT/PNT
information into an equivalent GPS RF signal in real-time, and without requiring the use of any
external equipment such as a PC etc.
The JLT RSR GNSS Transcoder™ defines a unique new product category in the market allowing
embedded retrofit of any GPS receiver to modern GNSS signals by converting standard GNSS or
positioning signals into a legacy L1 GPS RF signal. The transcoding process is performed in
real-time using embedded next-generation JLT-designed GPS simulator technology. The device has a
miniature form-factor (1.6 x 2.3 x 0.5 inches for the non-CSAC version) with mininal power
consumption (<1.1W w/o CSAC typically) and does not require any external equipment other than a
power source to operate. The self-contained real-time hardware simulation feature sets it apart from
competitive GPS/GNSS simulators that either require an external computer for signal processing and
control, or are based on passive record-and-playback technology that is highly inflexible.
The RSR GNSS Transcoder™ is a full-constellation, fully-integrated, low SWaP-C Real-Time
10-channel GPS Simulator allowing transcoding of any Position, Velocity, Timing (PVT), or
Position, Navigation, Timing (PNT) data into a legacy GPS L1 C/A code RF signal with up to ten
satellites being simulated in real-time. The Transcoder optionally has an integrated Cesium Chip
Scale Atomic Clock (CSAC) for atomic holdover performance, and is the first fully-integrated
real-time miniature embedded GPS full-constellation simulator on the market. The RSR GNSS
Transcoder™ allows easy retrofit of legacy GPS receivers with the latest generation GNSS signals
such as SAASM, M-Code, Glonass, Galileo, BeiDou, QZSS, or any other emerging GNSS signal, as
well as adding Inertial Navigation System (INS) and CSAC holdover capability to existing legacy
GPS equipment.
Application examples of the RSR GNSS Transcoder™ range from upgrading multiple GPS receivers
such as the various DAGR receivers inside a military vehicle to receive the RF signal from a single
RSR GNSS Transcoder™ and thus only requiring one RSR GNSS Transcoder to provide assured
PVT from only one SAASM-keyed receiver rather than all the DAGR receivers in a vehicle having
to be keyed etc, to retrofitting legacy GPS receivers for Galileo, Glonass, BeiDou, SBAS, M-code, or
SAASM capability, all by simply replacing the existing GPS antenna with the RSR GNSS
Transcoder™ and connecting a suitable GNSS receiver as a front-end to the RSR GNSS
