The U.S. Department of Transportation will host a third workshop to continue discussions of the GPS Adjacent Band Compatibility Assessment on March 12.
The workshop will focus on the following topics:
Identification of GPS and GNSS receivers to be considered for testing that are representative of the current categories of user applications
Discussion of a GPS/GNSS receiver test plan.
Anyone interested in presenting on either or both of the above topics should contact Stephen Mackey by March 2.
The workshop will be held 8:30 a.m.-3:30 p.m. PDT at Aerospace Corporation, 2310 E. El Segundo Blvd., El Segundo, California.
