MAPS Fight Tonight
Assured Positioning, Navigation & Timing (APNT) System
The GPS Source Mounted Assured PNT System - Fight Tonight (MAPS FT) system provides trusted and validated positioning, navigation, and timing data from GPS M-code signals. The system can operate in degraded and denied environments through use of additional PNT sensors. It allows a platform to rapidly transition to an APNT architecture from legacy and obsolete GPS systems.
MAPS FT creates and distributes digital PNT data, including IS-GPS-153, NMEA, 1PPS, and HAVE QUICK, to as many as eight independent client systems via RS232 or RS422 serial connections. MAPS FT also supports PNT distribution via Ethernet by way of VICTORY protocol.
Provides rapid transition to anti-jam, M-code protected APNT solution
Designed to reuse existing mounting provisions to reduce retrofit time to under 1 hour
Continuously distributes assured PNT data to vehicle end-point devices
Uses ethernet and serial protocols
Maintains PNT integrity in GPS degraded and denied environments
Accepts input from any anti-jam antenna for increased PNT assurance
ED3M is a COTS PNT hub providing SAASM or M-code protected GPS data. ED3M with VCAM installed retains 100% compatibility with all standard DAGR mount accessories and occupies the same space claim as the DAGR.

VICTORY CSAC Accessory Module (VCAM) is an optional module from GPS Source's existing family of solutions that fall under the Enhanced D3 product line. The VCAM integrates various non-GPS sensors to support a complete positioning, navigation, and timing (PNT) assurance capability. Designed as an open system, it allows integration of other products that support non-GPS solutions for PNT including an Inertial Navigation System (INS), Chip Scale Atomic Clock (CSAC) and software designed for electronic surveillance / electronic protection (ES/EP). Cutting edge VCAM technology integrates all timing and positioning solutions into one entity, allowing for seamless change from one source of timing data to another.
Key Features
- Internal Chip-Scale Atomic Clock (CSAC) for resilient time capability, provides precise time to within 100 ns of UTC when GPS available, and within 1 μs of UTC for up to 8 hours in a GPS denied environment
- Elec. Surveillance / Elec. Protection capability with Talen-X, Inc. Broadshield™ ES/EP application for detection of threats and validation of GPS data signals
- Designed to operate with Fixed Radiation Pattern Antenna (FRPA) that feeds signal data to dual GNSS receivers, confirming integrity and validity of military GPS signals
- Ethernet interface to host platform
- VICTORY Compliant 10/100/1000 Base-T per IEEE 802.3
- PNT Victory Messages:
- Direction Travel Message (TX)
- Orientation Message (TX)
- Position Message (TX)
- GPS Receiver Service (TX)
- PNT Victory Messages:
- Protected, GPS-synchronized Stratum 1 Network Time Protocol (NTP) Node
The Upper and Lower Bias-T Modules allow for 28VDC power to be routed to the Anti-Jam antenna on the existing RF line, eliminating the need for routing an additional power cable externally on the vehicle. The Bias-T configuration can be designed to support antennas with internal bias-Ts (single-cable solution) or secondary power connectors.
Key Features
- Reuses existing DAGR Extended Mount, mounting hole pattern, and DAGR power cable.
- Supports multiple Anti-Jam antenna vendors and models
- Environmentally qualified to MIL-STD-810 (Temperature, Shock, Vibe, Humidity, Water Intrusion)
- EMI/EMC qualified to MILSTD-461 (Conducted/Radiated Emission/Susceptibility)
- Currently fielded to hundreds of systems across multiple ground vehicle applications, within US Army and US Marine Corps.
- Low integration cost and reasonable hardware price allows for non-Tier 1 programs to outfit entire fleet quickly within standard budget constraints
MAPS Fight Tonight is compatible with multiple Anti-Jam Antenna Systems (AJAS). This allows the platform integrator to choose their AJAS based on cost and performance parameters suitable for their program.
The MAPS Fight Tonight system will compensate for time delay introduced by the AJAS with a simple drop-down menu in the FLOtalk configuration software that will persist across power cycles and power removal.
Key Features
- Integrates AJAS & FRPA to First and best line of defense against GPS interference, jamming, and spoofing
- Multiple AJAS vendors and models supported in current MAPS FT library
- Additional AJAS being added to support library regularly, including custom options
- Several mounting options exist for re-using RA-2 or FRPA-3EW hole pattern, easing integration overhead
- Single-cable solution (with bias-Ts) makes integration time and effort a non-factor, despite higher power requirements
