Technical approach

As reported
Solar-Powered Collars

GPS-enabled collars charge in daylight

Solar cells charge collars during day; operate at night. GPS tracks each animal continuously for virtual boundaries via app.

Satellite Connectivity

Direct-to-satellite via Starlink

New collars connect to Starlink satellites, not cell towers. Works anywhere cattle can see the sky.

Behavioral Monitoring

AI detects heat, illness, stress

Sensors track movement, rest, rumination. AI detects heat (for breeding) and illness before visible symptoms.

Mobile App Control

Manage herds from anywhere

The Halter app shows herd position, health alerts, and heat-detection data. Ranchers can move cattle or check a cow's status from their phone.
