GPS Modernisation

#1 Post by BanBan » Sat Jul 16, 2011 3:45 pm

CAPE CANAVERAL, Fla. (AP) - A Delta 4 rocket has rumbled into the early morning sky from the Kennedy Space Center at Cape Canaveral carrying a GPS satellite. The rocket lit up the sky at 2:41 a.m. Saturday after two consecutive days of delays for technical and weather issues. The United Launch Alliance Delta 4 rocket will place a navigation satellite into the Global Positioning System constellation for the Air Force. The GPS 2F satellites provide enhanced military signals that have greater accuracy and are more resistant to signal jamming. They also have some civilian applications and a longer life expectancy than the previous generation of satellites.
Hours ago after the usual mandatory weather delays, the Delta IV rocket carrying the second of the Block IIF satellite was launched into space. This is another step on the long roadmap of the GPS Modernisation program. This new satellite will be transmitting the new signals of the modernisation program. Of interest to us will be the new civilian signals L2C and L1C. The 8 satellites in Block IIR-M in orbit are already transmitting L2C but without the required message data yet. Maybe 10 satellites is not enough yet. The critical question for us end users will be:

Q. When can I go around tracking in Malaysia using a handheld that is able to process L1C and L2C simultaneously and giving sub-meter accuracy?

A. 2016!

Ahh... that is still a looong time away.

Wow, with submeter accuracy hopefully the GPS will know which lane you are in and advice to switch lanes if need be.
Mappers wanted. Read this to get started. Payment = Recognition = Priceless.
We don't just build maps. We build relationships.

This new addition to the gps constellation is satellite SVN 63 PRN 01. It will be going through its in-orbit testing for a few weeks before being put in service. The other satellite in this Block II-F is PRN 25. For those in the Klang Valley, you will hook up with this bird in the mornings.

The project involves new ground stations and new satellites, with additional navigation signals for both civilian and military users, and aims to improve the accuracy and availability for all users.
