Military GNSS Survey System

Achieve Your Survey Mission Using Fully Protected Military GPS Signals Supplemented by Civilian GNSS Signals:

  • Enjoy the benefits of industry-standard survey capabilities while operating in military environments
  • Don’t let the threat of jamming or spoofing interrupt your mission
  • No need to be exposed at the same location because you had to go back to complete the job
  • PPS GPS-S operates unclassified when keyed so the device and the data it records are not classified
  • PPS GPS-S provides full-time survey operations in military environments with no loss of capabilities or positioning accuracy.

Military GPS Supplemented by GNSS Data for RTK Survey

TAG’s Precise Positioning Service (PPS) Global Positioning System-Survey (GPS-S) system has been specifically designed to address the stringent requirements of military survey missions including geodetic, construction, airfield, and field artillery survey. PPS GPS-S provides precise GPS positioning accuracy with a military-grade GPS receiver to provide spoofing and jamming protection. The GPS receiver is supplemented with data from other Global Navigation Satellite System (GNSS) constellations to increase accuracy, integrity, and service availability. PPS GPS S gives the military surveyor the tools they need to complete their missions with minimum time-on-station even in the face of GPS signal interference, attempted spoofing, or Electronic Warfare (EW).

At the core of the PPS GPS-S system is TAG’s rugged tablet computer, the TC-301 TAG Commander. The TC-301 integrates both military GPS and civilian GNSS receivers, advanced Real-Time Kinematic (RTK) signal processing technology, a miniature military grade wireless radio, and an Intel® embedded low power multi-core processor, housed inside a rugged military grade tablet with a 7” touchscreen display and dual hot-swappable long-life batteries.

The high-precision, military GPS receiver provides GPS signal assurance and security with enhanced noise and signal rejection capabilities. The advanced integrated radio and RTK technology provides corrections for centimeter-level real- time positioning accuracy. In stationary mode and utilizing post- processing software, PPS GPS-S delivers millimeter-level accuracy. PPS GPS-S features Carlson® SurvPC Mil, a powerful commercial survey software for RTK survey systems and Total Stations that has been customized to run on TAG’s GNSS Controller.
