MEETING POSTPONED to December 10th @ 5:30pm

Due to inclement weather conditions, we have postponed our next meeting until Thursday, December 10th.  Meeting will still be held at Infinity Systems Engineering, 13560 Northgate Estates Drive, Colorado Springs, CO 80921-7654 and begin at 5:30pm with free pizza.

We are honored to have Mark Crews (former GPS chief engineer at GPSW and currently Chief Technology Officer with ITT Space Systems) as our guest speaker during the meeting with the topic of ADS-B and how GPS supports this concept.

ADS-B, or Automatic Dependent Surveillance-Broadcast, is a key component of the FAA’s GPS satellite-based NextGen program, intended to replace the nation’s aging network of ground-based radar sites in the air traffic control system. The new system as designed will be 10 times more accurate than radar, according to the FAA.  ADS-B uses GPS signals to determine aircraft position. The code containing a plane’s flight data is automatically broadcast from the aircraft’s transponder once per second. Aircraft equipped to receive the data and ADS-B ground stations up to 200 miles away receive the broadcasts. Ground stations add radar-based targets for non-ADS-B-equipped aircraft to the mix and send all of the information back up to equipped aircraft, along with information on weather and flight restrictions. This data displays on cockpit screens and air traffic control displays.

The presentation will be posted to the RMS-ION website ( prior to the meeting and dial-in information is 1-800-977-8002, code 58856129#, if you are unable to attend in person.
