Geography of “TNS-0” successful Contacts via GLOBALSTAR System
Total period of active work – 68 days. Overall lifetime – 5 months First-ever application of new satellite control technology - through low-orbit satellite communication system GLOBALSTAR (24% of the contacts were successful) First-ever experimental determination of GLOBALSTAR restrictions First-ever satellite serviceability monitoring by means of the International space search & rescue system (COSPAS-SARSAT)
Total period of active work – 68 days (up to 5 June 2005) Overall lifetime – 5 months (up to the end of August 2005) Successful testing of the experimental nanosatellite platform and miniaturized on-board devices (solar sensors, lithium power-supply batteries, on-board controller, etc.) First-ever application of the new satellite control technology through the global satellite communication system GLOBALSTAR: - nearly 90 contacts via GLOBALSTAR (24% of them - successful) - stable control of all processes on board of “TNS-0” - experimental determination of GLOBALSTAR restrictions (due to non-global coverage of Earth surface by actual GLOBALSTAR constellation and Earth stations, absence of roaming for several Earth regions, not a full adaptation of GLOBALSTAR modem to on-board operation, etc.) Successful “TNS-0” serviceability monitoring by means of the International space search & rescue system (COSPAS-SARSAT)
Future Space Systems on the base of “TNS” Nanosatellites
Space remote sensing System “Lokon”:
- Constellation including 4-6 Nanosatellites
- Orbits: 600…700 km (Height), 98º (Inclination), 4-6 Orbital Planes
- Three visible spectral Ranges (RGB)
- Observation Width – 250…300 km, linear Resolution – 50…100 m
- Delivery of Space Monitoring Information (Images) to Users 1 to 2 Times each Day directly in the monitored Locality
- Application of commonly used Personal ground-based Stations (F = 1,7 GHz, Aperture Dia 2,5 m) to receive Space Monitoring Information
- Wide Scope of Applications for “Lokon” Monitoring Information (Ecology, Emergencies Mitigation, Agriculture, Fishing, Natural Resources, etc.)
Low-orbit Space Communication System “KOSKON” including 6-12 Nanosatellites for gathering of global Emergencies Monitoring Information and its transfer to central & local rescue Services
