2010-02-25 OAUSA Net - GPS Basics

[toms]

This week's net will discuss the GPS componets in the sky and on the ground and a little bit of how it works. We are counting on those of you who are experts to jump in and help out!

Update
We reviewed the 3 components of the GPS – Space, Control and Receivers. We discussed the basic principles and issues that cause errors as well as the WAAS to provide a 5 fold improvement in accuracy. We discussed new systems planned in Europe and Russia and planned upgrades to the USA system for 2013 and 2021. The net was almost 2 hours with 36 check ins.

On our main page, it says " Outdoor Adventure USA radio net on Keller Peak repeater, Thursdays at 7:00pm"
Has the start time for the net changed recently, or this incorrect?
We better get that changed if it's incorrect...

Thanks Craig. I'll get that corrected.

The correct start time is 7:30PM.

More Satellites En Route

by Modern Hiker on February 26, 2010

Losing GPS signal is a common and frustrating problem for hikers who regularly use their GPS receiver to track progress – yours truly included. We all know that narrow canyons and thick tree canopy can cause signal loss, but other times it can go out even if you have a clear view of the sky. I’ve previously written about this loss of accuracy problem, and how the government was a bit behind on their satellite maintenance, but now it seems like someone’s pushed enough paper to get things moving.

Spurred by GPS signal issues in the rugged terrain of Afghanistan, the military’s Strategic Command has ordered a “satellite surge,” calling for three new GPS satellites in orbit, bringing the total number to 27. The first one has already been launched, and the remaining two are slated to launch by next January – a full year ahead of schedule.

Civilian GPS enthusiasts use the same network of satellites the military does, albeit with a limit on its accuracy, so we outdoorsy types may see an improvement in reception over the next year as the new satellites are brought online.

Very interesting...

The orginal directive to implement the new satellites (GPS III) was approved by Congress in 2000....designed to be in effect by 2013, and bonuses to contractors if completed by 2011...wonder if this is from the same Congressional directive...
