Equipment Problem Delays First GPS IIF Launch

A ground equipment problem has caused a 24-hour delay in launch of the first GPS IIF satellite (GPS IIF-SV1).

Originally scheduled for late May 20, the launch attempt has been reslotted to a May 21 launch window of 11:25 to 11:43 p.m. (EDT)

During normal processing for the launch from Cape Canaveral, Florida, mission managers determined that a piece of ground support equipment used to control one of the swing arms on the fixed umbilical tower was not operating correctly and needed replacing.

Replacing the GSE component will add one day to launch processing, according to the United Launch Alliance managers. This will be the first launch of a GPS satellite on the Boeing Delta IV rocket.

U.S. Air Force Prepares First IIF GPS Satellite for Launch on May 21

Launch of the first GPS Block IIF (follow-on) satellite is currently scheduled for May 21 from Cape Canaveral aboard a Delta-IV Evolved Expendable Launch Vehicle (EELV), with a destination in the constellation’s B2 plane and slot.

The IIF-1 SV (space vehicle) is at the launch site and fueled. A final IIF launch mission dress rehearsal (MDR) was scheduled to take place during the weeks of April 26 to May 7.

GAGAN Delayed Again

India’s first GPS/SBAS payload, the GAGAN (GPS-Aided Geo-Augmented Navigation system) transmitter on the GSAT-4 geostationary satellite, disappeared into the Bay of Bengal on April 15 when its ill-fated GSLV-D3 launch vehicle veered off course.

The Indian Space Research Organization’s GSAT-4 satellite carried a communication payload of multi-beam Ka-band pipe and regenerative transponder and a navigation payload in C, L1 and L5 bands.

A key part of India’s GPS augmentation plan, the failure will further delay civil aviation modernization.

EC Liberates Galileo ICD Signal Specification

Today’s (April 13) release of an updated “Galileo Open Service Signal-In-Space Interface Control Document” (OS SIS ICD) freed the key specification document in two senses of the word: receiver manufacturers, application developers and service providers may now use the ICD as an official — not draft — guide to their work, and they may do so at no cost

The t’s have been crossed and the i’s dotted to the satisfaction of lawyers and politicians — and the relief of designers and system integrators eager to begin work on Galileo-capable products without fear of having substantive changes in the specifications and legal or financial difficulties for moving ahead.

FAA Predicts Erosion of GPS WAAS Service Due to Intelsat GEO Failure

[updated April 13] Federal Aviation Administration (FAA) officials say that loss of control over an Intelsat geostationary (GEO) carrying a GPS Wide Area Augmentation System (WAAS) transponder could subject users in the National Air Space (NAS) to temporary outages for the rest of this year, beginning within the next two to four weeks as the GEO drifts out of a useable orbit.

Intelsat S.A. announced the anomaly in Galaxy 15 (G-15) on April 8. Although the communications services provided by G-15, located at 133 degrees west longitude (WL), have not been affected, according to Intelsat, the satellite apparently is not responding to commands by controllers. The anomalous condition began on April 3, according to the FAA.

The Luxembourg-based Intelsat is moving an older spacecraft (G-12) that serves as a backup for G-15 from its location at 123 degrees WL. However, G-12 does not have an L-band transponder, which is needed for WAAS transmissions.
