Warp Server is a spacecraft telemetry processing component compatible with NASA's Open MCT. Open MCT (Open Mission Control Technologies) is a next-generation mission control framework for visualization of data on desktop and mobile devices. Warp and OpenMCT are developed at NASA's Ames Research Center, and are being used for spacecraft data analysis as well as planning and operation of experimental rover systems.
Warp Server takes binary telemetry packets compatible with the CCSDS international standard and makes them available to Open MCT via REST and WebSocket interfaces. Because Open MCT does not decommutate (decode) binary packets, Warp performs this function using a telemetry dictionary before sending it decoded telemetry values.
Warp can run in several modes:
- Realtime mode
In realtime mode, warp receives packets from one of several kinds of sources (described below),
- Session mode
In session mode, Warp loads a database containing a set of previously-recorded telemetry packets, called a telemetry session, and responds to queries about them via a rest interface. These queries are usually of the form 'return the values of these telemetry points over this interval of time'. Before running warp in session mode, the program can be used to build the packet database from another source like a binary file or a directory of files.
- Combined mode
In combined mode, warp receives a realtime packet stream, builds a packet database on-the-fly, and responds to both REST queries and WebSocket session requests.
