Compatibility Test Set

CTS Logo


• Produce a test set that performs compatibility, interface and end-to-end testing of user radios operating over the SCaN infrastructure.

GRC Scope:

• NASA GRC is developing a Compatibility Test Set (CTS) to verify RF and Data Link compatibility, interfaces and enable end-to-end testing of user radios with the Space Network (SN) at S and Ka-Bands.

CTS Mission Context:

The CTS will be connected to the space radio, referred to as the Device Under Test (DUT), during pre-flight testing via an RF interface. This RF interface is for the forward (radio receive) and return (radio transmit) paths. The CTS will provide sufficient emulation of the Space Network (SN) communications interface and functions to enable compatibility testing of the DUT without accessing the operational SN. Compatibility testing consists of running a DUT-specific suite of communication tests to verify that the DUT can operate within the operational parameters of the SN. End-to-end testing of space radios will be enabled by the CTS RF TDRS Relay capability. During end-to-end testing the CTS relay will provide the necessary functions and capabilities to relay signals to/from the DUT and an on-orbit Tracking Data Relay Satellite (TDRS).
