The objective of the TDAMMComms SAG was to outline necessities, based mostly on the science drivers, for communications techniques to allow fast commanding and downlinking of information for future NASA TDAMM missions. The TDAMMComm SAG welcomed enter from neighborhood stakeholders, together with these concerned in mission ideas at present in improvement.
About TDAMM SAG
Area-Primarily based Astrophysics Requires Mission Communications With the Floor
Within the burgeoning discipline of time area and multi-messenger astrophysics (TDAMM), the science drives the frequency of this communication each for downlinking knowledge and uplinking instructions.Â
In the previous few many years, NASA has supplied a wide selection of choices for communications, together with Close to Area Community (NSN), which consists of Direct-to-Earth (DTE) floor stations for speaking with missions in near-Earth orbits; the Area Relay (SR), which operates a fleet of geostationary satellites referred to as the Monitoring and Information Relay Satellite tv for pc System (TDRSS); and at last the Deep Area Community (DSN) for speaking with missions at bigger distances (e.g., Planetary Distances, Lagrange factors).
The present fleet of rapidly-communicating TDAMM missions (e.g., Fermi, Swift, NICER) have utilized TDRSS property to carry out low-latency alerts and commanding which have enabled transformational TDAMM science. Nevertheless, sooner or later it has been communicated that TDRSS will probably be decommissioned and changed by a business service by 2030, with some interval of overlap. The objective of this SAG is to, based mostly on the science drivers, outline necessities for comms techniques to allow fast commanding and downlinking of information for future NASA TDAMM missions.
The SAG will think about varied questions regarding how future communications options will be developed to higher assist TDAMM missions. These questions embrace wanting on the science drivers that may outline future comms wants; the wants for missions in quite a lot of orbits; wanting into bandwidth and latency necessities for future TDAMM missions; the difficulty of price of comms for TDAMM missions; the necessity for prime availability and versatile scheduling of comms; and the way the way forward for communications will be higher marketed to proposers.
