Abstract	NASA's mars reconnaissance orbiter (MRO) was launched on August 12, 2005 and was inserted into Mars orbit successfully on March 10, 2006. From September 2005 through January 2006, the Ka-band signal from the spacecraft was tracked several times by NASA's deep space network (DSN). During these tracks a number of Ka-band functions for both the spacecraft and the ground systems were tested. These tests were performed to assess the readiness of the ground system and spacecraft to support Ka-band demonstration activities during MRO's primary science phase (PSP). As a result of these tests a number of important lessons were learned regarding the performance of the Ka-band link and the performance of the ground equipment. This paper presents the performance of the ground antenna pointing, delta differential one-way ranging (DeltaDOR) performance and the telemetry performance of the Ka-band link. These results indicate that the extra effort for pointing calibration of the ground antennas at Ka-band is extremely useful; Ka-band shows potential for improved DeltaDOR performance and the models for Ka-band performance of the ground station microwave noise temperature are very accurate.
