The Multitronix Kate-3 tracking system was used by Evolution Space on a test flight to over 188,000 feet. This was an S45000 single stage rocket. Kate-3 controlled all flight operations as well as providing GPS tracking and telemetry downlink. More information including a video and some photos is available here.
This test flight demonstrated the unlimited altitude capability in the Kate-3 GPS tracking system. The maximum altitude was measured by the Kate-3 TelemetryPro GPS to be 188,444 feet. This is above the 164,000 feet operating limit of other GPS tracking systems. Furthermore, the Kate-3 system maintained a continuous telemetry downlink data stream during the entire flight. No data packets were lost even at over 188,000 feet.
