In 1997 CAST discontinued the use of the Stanford Telecommunications (STeL) GPS signal generators in our products in lieu of a new single board GPS signal generator that was produced by Rockwell Collins. The “older” STeL configuration required two 10.5 inch high chassis and a separate controller computer to provide a 10 channel C/A P(Y) GPS constellation. The single board 10-channel L1/L2 C/A P(Y) code capability enabled CAST to house a complete system solution in a much smaller package at a much lower cost to our customers.
