Satellite IoT

Field device data reaches the customer’s business systems over satellite links. This covers field access, narrowband adaptation, protocol conversion, cloud forwarding and long-term operation.

Seven stages

Stages in blue are developed in-house.

1Field devices
Sensors, meters, phones
2Link selection
GEO, LEO, NTN, cellular, mesh network
3Narrowband adaptation
Links of a few Kbps, a few hundred bytes per message: compression, fragmentation, priority-based sending
4Protocol conversion
In-house NRMP (NTN Reliable Messaging Protocol) to reduce protocol overhead
5Cloud forwarding
Satellite data, once landed, goes into the customer platform and intranet
6AI agents
Satellite messages processed in the cloud to move business workflows forward
7Reliability and power
Low temperatures, no mains power, unattended; -40 to 80 °C, salt-spray and corrosion resistant

Protocol conversion

Conversion between field protocols, satellite link protocols and business-side protocols.

Field side

Modbus RTU / TCP
Proprietary serial protocols
LoRa / NearLink device messages

Satellite link

NRMP

Compression · fragmentation · priority
Caching and resending
De-duplication by sequence number and timestamp

Business side

MQTT
HTTP API / SDK
Customer cloud platform / intranet

Priority sending: Alarms, SOS and flight-control commands go first; images and logs follow.
Resume after interruption: Data is cached locally while a link is down and sent once it recovers.
Best-of-multiple paths: The same data is sent over two paths at once; the receiver keeps one copy by sequence number, timestamp and checksum.
Link logs: The status, fault cause and start and end times of every link are logged for later review.
