LOCATION
TRACKING
Multi-constellation GNSS, LTE-M and NB-IoT cellular, UWB indoor positioning, GSMA SGP.02 M2M eSIM, years-long primary battery firmware, and platform API integration — engineered for the field, not the bench.
The Engineering Problem
Asset Tracking Hardware That Performs in the Field — Not Just on the Bench
A tracker's bench specifications and field performance are entirely different numbers. Battery life at room temperature in open sky means nothing inside a -25°C refrigerated trailer acquiring through a metal roof on a retransmit-heavy NB-IoT network. We design from the actual deployment environment backward — power budget, GNSS strategy, and network attachment time all engineered for where the tracker actually runs.
Indoor-outdoor positioning convergence demands trackers that move seamlessly from GNSS in the yard to UWB on the warehouse floor. GSMA SGP.02 eSIM maturity enables cross-border fleet tracking without SIM swaps. Pharmaceutical GDP intensification requires millisecond-synchronized temperature and GPS records — not two separate data streams correlated in post-processing.
Fleet, supply chain, cold chain, healthcare, construction, and oil and gas programs all need a tracking hardware partner who understands deployment environment performance, power budget engineering, and platform integration at the firmware and API level — not just a module supplier.

Vehicle, Fleet & Equipment Tracking
The most mature segment of asset tracking — and the most demanding for a hardware partner to serve credibly.
Fleet specification-to-field gaps are well documented: 4-year battery life becomes 14 months at -20°C, J1939 integration can't reach proprietary OEM PGNs, eSIM requires manual carrier configuration at every border. Dead reckoning illustrates why vehicle tracking requires real sensor fusion engineering — IMU-only heading accuracy degrades over a 400m tunnel transit and produces a visible map jump at exit. Wheel odometer coupling, Kalman filter weighting, and GNSS re-acquisition sequencing all determine whether the track is smooth. We've engineered this at the algorithm level.
Indoor Positioning & Supply Chain Visibility
Sub-30cm accuracy where GPS does not work — and seamless continuity through the dock door.
UWB sub-30cm accuracy in steel-racking warehouses requires CIR-based first-path detection — reflected paths arrive within nanoseconds of the direct path in a racking environment, and selecting peak amplitude instead of first arrival produces systematic ranging error. Anchor geometry, NLOS detection weighting, and WMS coordinate frame transformation must all be correct. Open-space spec compliance is not the same as warehouse deployment accuracy.
Cold Chain, Condition Monitoring & Sensitive Asset Tracking
GPS location alone is not sufficient for pharmaceutical cold chain compliance — and Ankh knows why.
GDP compliance requires temperature and GPS at the same timestamp — not two separate data streams correlated in post-processing. The synchronization must happen inside the firmware's logging architecture, not on a server. Li-SOCl2 delivers 40% less capacity at -20°C than at room temperature, so a tracker claiming 5-year battery life on a room-temperature datasheet may deliver 3 years in a frozen pharmaceutical trailer. We specify and validate cold chain battery life at the actual deployment temperature.
Why Asset Tracking Companies Choose Ankh Innovations
Power Budget Engineering as a Design Discipline
Battery life is determined by GNSS acquisition current, cellular transmit power, component sleep current, battery chemistry temperature coefficient, and deployment temperature — not tuned in firmware after the hardware is built. We build the power budget at the first architecture review and validate it in a thermal chamber before the design is committed.
Deployment Environment Performance, Not Bench Performance
GNSS sensitivity through metal enclosures, cellular antenna performance at real crew installation angles, BLE accuracy in steel-racking warehouses, NB-IoT attach time in under-optimized carrier regions — we characterize performance in the actual deployment environment, not an anechoic chamber.
Multi-Technology Seamless Positioning Across Environments
Supply chain visibility breaks at the yard-to-dock-to-warehouse boundary. We design the handover firmware and platform data model that maintains continuous location across technology transitions — GNSS outside, BLE at the perimeter, UWB at pallet granularity inside — without location voids.
Platform Integration Built In, Not Bolted On
Samsara, Verizon Connect, Geotab, and Trimble each have specific onboarding processes, data formats, and API authentication models that must be implemented in tracker firmware before the first location event appears. We build platform integration as part of the development program — not as a post-delivery project.
