The Global Positioning System (GPS) Central Engineering Activity (CEA) laboratory is the Navy’s premier navigation laboratory for GPS user equipment and GPS modernization research, development, test and evaluation (RDT&E).

Through real-time simulation of Global Navigation Satellite System (GNSS) signals, interference/jammers, host vehicles, and platform sensors, the facility exercises GNSS receiver hardware and software dynamically under precise and repeatable laboratory conditions. The CEA facility supports multiple simultaneous GNSS signal and jammer control simulations for all-in-view, wavefront, attitude determination testing, differential testing, etc. 

The CEA’s extensive capabilities include:

  • Modernized GPS environment (GPS M-Code, L2C, L5)    

  • WAAS, LAAS, Pseudolite signal environments       

  • SIGNaL, which allows simulated high dynamic testing of EGI receivers by injecting simulated inertial sensor data directly into the receiver’s processor         

  • Numerous host vehicle interface emulations (fighter/attack aircraft, small/large surface ships)

  • Numerous sensor models (Doppler Radar, BARO, GyroCompass, INS/IMU)

  • Numerous interface models (1553, ARINC 429/575, RS-422)

  • Multiple antenna array electronics RDT&E

  • Attitude determination simulations

  • Differential simulations testing

  • Interference/jamming/spoofing environment

  • GPS Receiver Application Module (GRAM) Universal Test Station (GUTS) form factor verification environment      

  • Anechoic chamber (antenna testing)

  • Facilities for classified programs

  • Links to C4ISR laboratories and facilities  

The CEA continues to develop new ways to ensure Test and Evaluation (T&E) capability for a variety of customers.   SSC Pacific has developed new tools and concepts to meet the future test needs of the navigation community, including GPS Modernization, Navigation Warfare (NAVWAR), and other research and development areas. The GPS CEA has developed an advanced simulation capability for generating waveforms such as GPS M-Code, L2C, and L5, thus allowing simulation in all three signal-in-space modes  of IF, RF, and digital. The CEA has also developed the test capability that supports algorithm verification and validation of the functional and performance testing of the GPS receivers. The CEA is designed to grow and evolve to meet future positioning, navigation, and timing requirements.
