Abstract:	The results of a differential GPS kinematic test conducted on The University of Calgary’s Kananaskis test traverse with two Ashtech LD-XII receivers during Spring/Summer 1990 are reported. The LD-XII receiver is a state-of-the art unit which can track the Ll code and carrier on all-in-view satellites and the L2 carrier on the same satellites. The results obtained with Ashtech’s KINSRVY (Ferguson et a1.,1989) software are compared with The University of Calgary’s SEMIKIN software (Cannon, 199O). KINSRVY uses an independent double difference least- squares algorithm at each epoch while in kinematic mode and a double difference adjustment in static mode at each station. SEMIKIN employs a Kalman filter to process the kinematic measurements and a least-squares adjustment to process the static carrier phase measurements. Results of each program are compared with the independently surveyed traverse for semi-kinematic mode and with each other in pure kinematic mode. Agreement at the centimetre level have been achieved in both pure kinematic and semi-kinematic mode. The overall performance of the Ashtech LD-XII receivers for kinematic surveying is discussed together with the capabilities of both software packages.
