Receiver Independent Exchange (RINEX)

We are happy to announce that our permanent base station is now operational. We call it FEI1!

National Height Modernization

We are a member of the National Geodetic Survey Cooperative CORS network

The FEI1 receiver system is capable of collecting static data while performing Real Time Kinematic (RTK) simultaneously, either by radio modem and/or cellular phone communication. The cellular connection capability extends RTK operational range to the digital service provider area of the entire San Antonio area, avoiding radio frequency interruptions.

Our advanced CORS system operates with a radomed choke ring antenna designed by the Jet Propulsion Laboratory, capable of providing 3mm/0.02ft +/- 0.5ppm accuracy when post-processing static data with the proprietary software.

To improve your capacity to post-process static data immediately, we are offering Receiver Independent Exchange (RINEX) formatted data daily every hour on the hour at no cost. Click on RINEX to download it from our web site on the Internet.

FEI excels in offering professional GPS services to our community.
