IoT & M2M Constellations
S-band bi-directional TT&C for IoT and M2M constellations. Orbitvein's scheduling API supports multi-NORAD contact sequencing — submit a command queue per spacecraft, and the system allocates contact time slots across the pass window automatically. Scale from 5 to 50+ spacecraft without adding ground operations headcount.
Designed for Constellation-Scale TT&C
2.025 – 2.120 GHz Uplink / Downlink
Orbitvein's S-band systems support both uplink command transmission and downlink telemetry capture. G/T values of 18.4 to 22.1 dB/K are suitable for IoT payloads with link margins designed around 50–200 kbps data rates. RHCP and LHCP polarization selectable per contact.
Queue Commands Across Multiple Spacecraft
IoT constellation operators often need to uplink firmware updates, configuration changes, and telemetry retrieval commands to dozens of spacecraft within a single pass window. Orbitvein's scheduling API supports multi-spacecraft contact sequencing: submit a command queue per NORAD ID, and the system allocates pass time slots automatically across the contact window. No per-spacecraft human operator required.
High-Frequency, Short-Duration Contacts
IoT missions typically require many short contacts (3–7 minutes per pass) rather than the burst 10-minute sessions used for EO payloads. Orbitvein's scheduler is optimized for high-frequency low-duration contact patterns: the API accepts recurring weekly schedule templates per spacecraft, and conflict resolution handles plane-phasing scenarios where multiple spacecraft from the same constellation arrive at a station within minutes of each other.
Typical IoT Contact Schedule
| Spacecraft | AOS | LOS | Duration | Command |
|---|---|---|---|---|
| IOT-SAT-001 | 14:22:05 UTC | 14:26:41 UTC | 4m 36s | TLM_DUMP + CFG_UPDATE |
| IOT-SAT-002 | 14:29:18 UTC | 14:33:47 UTC | 4m 29s | TLM_DUMP |
| IOT-SAT-003 | 14:41:03 UTC | 14:46:22 UTC | 5m 19s | FW_UPLOAD + REBOOT |
"Managing TT&C contacts for a 24-spacecraft plane was a scheduling problem our previous provider's portal was not designed for. Orbitvein's multi-NORAD API let us submit the entire plane's contact schedule as a single JSON payload. Our operations team went from 3 hours of manual scheduling per day to under 15 minutes." — Operations Lead, Aphelion Networks
