About
The Hubble Network is a hybrid global IoT connectivity platform that allows any device equipped with a standard Bluetooth Low Energy (BLE) chip to transmit data via a combination of terrestrial gateways and Low Earth Orbit (LEO) satellites — without modems, custom antennas, or hardware modifications. By updating firmware via Hubble’s lightweight SDK, off-the-shelf BLE chips from Silicon Labs (MG24) and Texas Instruments (CC2340/CC2755x) can immediately access the network. This capability was previously considered technically impossible; Hubble’s March 2024 first Earth-to-space Bluetooth connection validated the concept.
The terrestrial layer comprises 100 million+ passive scanning gateways — including smartphones, infrastructure devices, and fixed access points — covering 2,500+ cities across approximately 3 million square miles, providing indoor, urban, and in-transit visibility. The satellite layer currently comprises 7 operational satellites at approximately 600 km LEO altitude, with four launched on SpaceX’s Transporter-14 rideshare in 2025. The constellation is planned to grow to 60 satellites by 2028, enabling near-real-time global coverage with revisits approximately every 15 minutes.
Data payloads are limited to 13 bytes per packet, optimized for sensor telemetry (temperature, location, motion state, asset ID) rather than high-bandwidth applications. Geolocation accuracy is approximately one square kilometre. The proprietary Space-Cloud protocol underpinning satellite communication is 20× more energy-efficient than traditional satellite IoT, enabling multi-year operation from a single coin cell battery. End-to-end AES encryption is applied throughout, with rotating IDs for privacy. Customers retain full data ownership; the platform offers open REST API and modular SDKs with no vendor lock-in.
Primary target markets include asset tracking, shipping and logistics, cold chain monitoring, stolen vehicle recovery, rental equipment management, and warehouse/yard visibility. Hubble has raised $100 million in total funding including a $70 million Series B. Strategic partners include Life360/Tile, Silicon Labs, and Texas Instruments.
