A cluster of 6 micro satellites should be launched today from Vandenburg as payload on a minotaur vehicle The payload of each satellite is a GPS receiver. The initial orbit will be 500Km circular, inclination 71 degrees. The final configuration will be 1 satellite per plane, with the planes 24 degrees apart, at 800Km altitude. The mission is to observe the changes introduced in GPS satellite signals as the signals pass through the atmosphere.This will give atmospheric profiles in both the tropospheric and ionospheric parts of the atmosphere.
