Your dog bolts after something on a backcountry trails, your GPS tracker app spins, and the signal cuts out at exactly the wrong moment. The one moment you needed that $200 gadget to work, and it goes dark. Fi Ultra exists because LTE-based dog trackers fail precisely when panic sets in — in dead zones, on rural acreage, deep in wilderness where cell towers are a rumor. This New York-based pet tech company built the first consumer dog tracker powered by T-Satellite with Starlink, embedding the same Low Earth Orbit satellite connectivity used by emergency responders into a 68-gram collar module. Satellite tech that once required a bulky dish on your roof now clips onto your golden retriever.
Satellite Tracking Keeps Your Dog on the Map When Cell Service Can’t
Fi Ultra automatically switches between four connectivity layers so you never have to think about signal.
Fi Ultra cycles through LTE, Wi-Fi, Bluetooth, and Starlink’s T-Satellite network automatically — no manual toggling required. A dual-band high-accuracy GPS module handles precise real-time positioning while the Fi app delivers live maps, escape alerts, and safe-zone notifications. Dogs that wander off rural properties or chase wildlife on backcountry trails stay visible on your phone regardless of cell coverage.
- Connectivity: LTE + Wi-Fi + Bluetooth + Starlink T-Satellite (automatic switching)
- GPS: Dual-band high-accuracy module
- Durability: IP68 and IP66K water-resistance, built for dogs that swim, play in mud, or face harsh weather
- Dimensions/Weight: 75 x 40 x 25 mm; 68 g
- Battery: Approximately two days per charge via USB-C
Fi describes Ultra as solving the “fundamental problem” of pet tracking — dogs moving beyond cell coverage, according to Pet Age. The collar also packs Fi Callback, a training feature that emits sound and vibration cues to recall your dog without shock collars or separate devices. Tracking plus humane recall in one wearable is a genuinely useful combination for anyone heading off-grid with their dog.
The Trade-Offs: Battery Life and Subscription Cost Are the Catch
Two days of battery life is a steep drop from the weeks-long endurance of Fi’s previous collars.
Most GPS trackers promise always-on protection. Ultra delivers roughly two days per charge — a significant compromise versus Fi Series 3+, which lasts weeks or months. Fi frames Ultra as an active-use trip tracker rather than a set-and-forget daily collar, so plan your charging around your adventures. Pricing runs $199 hardware plus approximately $189 annually for new members, or $299 for existing Fi users upgrading. That subscription is mandatory for full LTE and satellite connectivity. Coverage remains U.S.-only for now, with international expansion plans still unconfirmed.
If your dog never leaves cell range, Ultra is expensive overkill. But if your adventures regularly outrun LTE, Fi Ultra currently stands alone as the only consumer dog tracker connecting to satellites, according to Tom’s Hardware. It snaps directly onto existing Fi Series 3 or Series 3+ collars, keeping the upgrade straightforward for current users ready to go genuinely off-grid with their life on road.
