Satellite Upgrades PlannedNov 28, 2007

Apparently the US military is planning some impressive updates to their existing satellite technology. In an attempt to maintain their dominance in the GPS arena they will be launching 8 new satellites bringing the total active ‘birds’ to 32. This new system, GPS III, is slated to have 500 times the transmitting power which promises to give greater reliability and higher resistance to jamming. It will also offer second and third frequencies to contain civilian signal, more robust signal transmissions and provide 1 meter accuracy.

This news comes on the heels of a recent announcement from the European Union that they have included 3.5 billion dollars in their budget for deployment of their Galileo project. Galileo is the global navigation system to be built by the European Union as an alternative to the US and Russian navigation systems. The system is to be operational by 2011-12.

Selective Availability RemovedSep 18, 2007

In a statement from the US Press Secretary ‘the President accepted the recommendation of the Department of Defense to end procurement of Global Positioning System (GPS) satellites that have the capability to intentionally degrade the accuracy of civil signals’.

Selective Availability was introduced by the US Military to make civilian GPS signals less accurate. Then in 2000 Selective Availability was turned off, which led to the growth of GPS technology for civilian use that we see today.

This decision means that future GPS satellites will not be required to be Selective Availability enabled, ensuring that it is permanent. Although GPS technology is firmly entrenched in consumer electronics, aviation, shipping and new products daily there was concern that with the option to turn Selective Availability back on it was a possibility.
