1. A method of recovering data included in a damaged differential correction message using a partial decode algorithm, said method comprising the steps of:
- locking on a current differential correction message;
testing said current message by using a plurality of standard parity tests and a modified parity test;
andutlilizing said testing information at the higher level integrity testing of said current differential correction message.

Abstract
The partial decoding algorithm for decoding the partially damaged differential satellite positioning system (SATPS) messages is disclosed. The algorithm is based on the modified parity test. The information included in the decoded messages can be used for the high level differential SATPS testing.
