Safety and proof, wherever mobile networks end.
SatPrahari is an Indian satellite IoT platform that tracks, protects and verifies people, vessels, vehicles and sensitive cargo — from the deep sea to the high Himalaya.
The people and goods that need monitoring most are out of reach.
Mobile coverage ends a few kilometres offshore, deep in forests and on mountain routes. When something goes wrong there, help is late — and in cold chain, missing or manipulated logger data hides losses until it is too late.
Fishing crews at sea
Boats lose contact 20–30 km from shore. In a cyclone or breakdown, families and authorities don't know where to search.
Vaccines, food & seafood in transit
Loggers go silent, get unplugged or are "adjusted". Cargo owners receive reports they cannot trust.
Forest staff & mountaineers
Guards patrol alone; trekkers face avalanches and altitude sickness — often with no way to call for help.
One rugged device. One secure platform. Any terrain.
A solar-powered device sends position, SOS alerts, messages and sensor readings through a licensed satellite network to the SatPrahari cloud — and receives warnings back.
- SOS button and pre-set messages from anywhere with a view of the sky
- GPS + NavIC positioning, cyclone and boundary alerts
- Temperature, door and tamper sensors; reefer-unit data
- Solar + LiFePO4 battery for weeks of autonomy
- Regional-language app and live dashboards; data hosted in India
Device
Rugged, waterproof unit on a boat, truck, box or person.
Satellite link
Short messages through a satellite network authorised for India.
SatPrahari cloud

People who act
Owners, families, cargo clients, control rooms and response teams.
Built once, configured for every frontier.
Fisheries
Live boat location, SOS, cyclone and boundary alerts, fishing-zone advisories and icebox temperature.
Cold chain
Tamper-evident temperature and reefer monitoring for pharma, vaccines, dairy, food and seafood.
Forests & wildlife
Guard safety and SOS, verifiable patrol tracks and early warnings in remote ranges.
Mountains & disaster response
Tracking and SOS for expeditions, trekkers, pilgrims and rescue teams.
Remote security operations
A rugged variant for remote posts, developed only through applicable formal channels.
Developing nations
Affordable, locally supported safety for coastal and remote communities across the Indian Ocean region and Africa.
Your transporter can't hide a breach.
Designed by people who have supplied transport refrigeration and data loggers to India's cold-chain industry — and seen how loggers are switched off or manipulated.
- Sealed backup power — power cuts trigger instant alerts
- Missing heartbeat raises an alarm; no "no network" excuse
- Dual probes detect a probe moved into ice
- Reads compressor, set-point and door data from the reefer unit
- Digitally signed readings go straight to the cargo owner
