ATSC engineers help install TDRS Ground Terminal at Guam

The Guam Remote Ground Terminal (GRGT) replaced the GRO Remote Terminal System (GRTS) in Canberra, Australia, continuing to provide closure of the Zone of Exclusion for the TDRSS Satellite Constellation, while significantly expanding customer service capabilities.

GRGT is an extension of the White Sands Complex (WSC) and will be operated exclusively from the Cacique ground terminal at White Sands, New Mexico. GRGT includes a single Space to Ground Link Terminal (SGLT) relocated from Cacique, an MA system using equipment relocated from GRO Remote Terminal System (GRTS) located in Canberra, Australia, and newly manufactured equipment - an 11-Meter antenna and a 4.5-Meter End-to-End test antenna. GRGT provides S- and Ku-band TDRS Telemetry, Tracking, and Command (TT&C) capabilities; two S-band Single Access (SSA) forward and return links; two Ku-band Single Access (KSA) forward and return links; one Multiple Access (MA) forward link; and two MA return links for customers.

Guam is the fourth TDRS Ground Terminal that ATSC assisted NASA in implementing:

The Guam Remote Ground Terminal (GRGT) met its scheduled acceptance date of June 9, 1998, and became fully operational on July 9, 1998.
