CAST Navigation of Tewksbury, Massachusetts introduced its SGX GPS Satellite Simulator. With its compact size — 7 × 11× 3 inches — and weighing in at just over 4 pounds, the SGX is CAST’s newest and smallest fully capable simulator to date. The new SGX replaces the CAST-SIMCOM Simulator which was a 17-inch, 50-pound simulator. The SGX lightweight portability operates on AC or battery power, features 16 channels of L1 C/A and P codes, and is extremely accurate and repeatable, according to the company. Features include touch screen, individual satellite power control, and start and stop scenarios with a touch of a button. The CAST-SGX is portable, affordable, lightweight and utilizes CAST long standing proven technology. CAST has been in the GPS simulation and support business for more than 25 years, designing, developing, manufacturing, and integrating innovative GPS/INS simulators and associated equipment for government, military, prime vendor, and consumer markets.
