Starlink-backed collar lets you track dogs anywhere, even without cell service

Fi unveils the Fi Ultra GPS collar, the first dog tracker to combine GPS with a cellular modem and Starlink satellite connectivity, so owners can see real‑time location data via an app even where cellular coverage is absent. When out of range, the device uses Starlink direct‑to‑mobile to relay a dog’s position, with geofencing alerts, and it can emit vibrations or sounds to coax the pet home, all powered by a multi‑day battery.

Mitigating Satellite RF Pollution and Scope Photobombs

Satellite constellations like Starlink are causing radio interference and optical photobombing issues for astronomers due to poorly designed antennas and spectrum leaks. While regulations are evolving to mitigate these problems, hardware updates and better standards are needed to ensure coexistence between scientific and commercial satellite uses, with ongoing efforts to improve antenna design and spectrum management.

Concerns Rise Over Crowded Low Earth Orbit

A new study warns that low Earth orbit is becoming increasingly crowded, with a significant rise in collision-avoidance maneuvers and space debris, raising concerns about the sustainability and safety of satellite operations, especially as the number of satellites is expected to grow substantially by 2030.
