TELEMATICS
Full-stack fleet telematics: multi-network J1939 decoding with proprietary OEM PGN libraries, FMCSA ELD compliance, GSMA SGP.02 M2M eSIM across 100+ countries, GNSS dead reckoning, and Samsara, Geotab, and Trimble platform integration.
The Engineering Problem
The Telematics Device That Only Decodes SAE Standard J1939 PGNs Delivers 30% of the Fleet Intelligence Your Customers Actually Need
Off-the-shelf telematics decodes SAE standard J1939 PGNs — which covers roughly 30% of what a modern commercial vehicle's CAN Bus actually carries. The engine hours, proprietary fault codes, and body controller parameters that fleet managers depend on live in OEM-specific PGN ranges that require reverse-engineered libraries to reach.
Fleet electrification brings battery SoH monitoring, range prediction, and charging infrastructure data that legacy J1939 hardware was never designed to handle. ADAS adoption and platform consolidation add further complexity — operators need a single device that captures all data streams from traditional and next-generation vehicle systems.
We design from the fleet intelligence requirement outward — which PGNs from which networks at which rate, which platform receives the data and in what format, and which operating conditions the device must survive. That sequence eliminates the rework that happens when hardware design begins before protocol and platform requirements are locked.
Fleet Telematics Categories We Build

J1939 & Vehicle Network Integration
Simultaneous decoding across up to 4 independent J1939 CAN networks per vehicle — chassis, powertrain, body builder, and trailer. Proprietary OEM PGN libraries for Freightliner, Peterbilt, Kenworth, Volvo, Mack, International, and Western Star reach the parameters SAE J1939-71 doesn't publish. OBD-II, ISOBUS, LIN, and 100BASE-T1 automotive Ethernet round out the full vehicle network stack.
GNSS & Positioning Architecture
Multi-constellation GNSS (GPS, GLONASS, Galileo, BeiDou) with dead reckoning via wheel pulse and 6-axis IMU — maintaining position accuracy for up to 60 seconds through tunnels and urban canyons. A-GNSS cold start, microsecond-accurate event timestamping, jamming detection, geofencing, and trip boundary detection from correlated engine and movement data.
Cellular Connectivity & eSIM
LTE Cat-1 for high-frequency reporting and video; Cat-M1 for lower-power deployments. GSMA SGP.02 M2M eSIM handles automatic carrier selection across 100+ countries — no SIM logistics. Dual physical SIM for primary/backup resilience, 2G fallback for emerging markets, and satellite interface for beyond-coverage operations.
Automotive Power & EMC Design
9–32V input covers mixed 12V and 24V fleet vehicles. ISO 7637-2 transient immunity handles load dump up to 150V — designed in from the first schematic, not the compliance campaign. Reverse polarity protection, battery backup for park-period operation, and sub-milliwatt sleep with wake-on-CAN, ignition, or accelerometer.
ELD & Regulatory Compliance
Full FMCSA ELD Technical Specification compliance — all 29 required data elements, CMV engine synchronisation, RODS generation, and Bluetooth/web services roadside inspection transfer. Co-driver simultaneous logging, personal conveyance, yard move, and adverse driving condition edge cases handled correctly — the ones that generate Additional Information requests when they're not.
Edge Intelligence & Trip Analytics
On-device trip segmentation, harsh event detection, and fuel efficiency calculation eliminate cloud round-trip latency for driving behaviour scoring. Accelerometer-based harsh braking and cornering with road surface vibration filtering prevents false positives. Local ring-buffer preserves complete trip data through cellular outages up to 72 hours.
Fleet Platform Integration
Native integration with Samsara Open API, Geotab SDK, Verizon Connect, Trimble Fleet Manager, and Motive — device provisioning, real-time telemetry, ELD data delivery, and AEMP ISO 15143-3 REST output all built into firmware. Custom REST and MQTT integration for proprietary platform development.
OTA & Fleet Management
Cryptographically signed FOTA with staged rollout by vehicle subset and automatic rollback on failure. Delta OTA minimises cellular consumption for fleet-wide updates. Zero-touch provisioning, remote configuration, anti-tamper detection, device health monitoring, and remote wipe for end-of-life or stolen vehicles.

Commercial Vehicle, J1939 & ELD Telematics
4-Network J1939. Proprietary OEM PGNs. FMCSA ELD Technical Specification. Samsara. Geotab. Trimble.
A mixed fleet of 1,400 trucks from 8 OEMs has 47 distinct vehicle configurations — each with different J1939 network architectures, proprietary PGN assignments, and DM1 fault mappings. Our gateways decode all 4 CAN networks simultaneously, with OEM-specific PGN libraries that reach the engine hours, fuel consumption, and fault descriptions that SAE standard decoding misses.
Construction, Mining & Agricultural Equipment Telematics
AEMP ISO 15143-3. ISOBUS. OEM-Agnostic. Mining Payload. Precision Agriculture.
Construction and mining fleets span multiple OEMs, each with a proprietary telematics platform that creates data silos. A device that decodes OEM CAN Bus messages and outputs to AEMP ISO 15143-3 breaks those silos — giving fleet managers one view of utilisation, fuel, and fault status regardless of manufacturer. We've built OEM-specific libraries for Cat, Komatsu, Volvo CE, Hitachi, Liebherr, JCB, Case, Doosan, and others.
UBI, Driver Safety & Specialist Vehicle Telematics
Harsh Event Scoring. AI Dashcam. AES-256 Encrypted. MIL-STD-810G. GDPR-Aware.
UBI telematics lives or dies on false positive rates. Multi-axis accelerometer harsh event detection cross-validated with GNSS speed derivatives — and filtered against road surface vibration frequencies — produces scores that hold up to actuarial review. Specialist government and military applications add AES-256 encrypted reporting, MIL-STD-810G ruggedisation, and GDPR-compliant data handling from day one.
Why Fleet Technology Companies Choose Ankh
J1939 Fluency Beyond the SAE Standard
SAE J1939-71 covers roughly 30% of what a commercial vehicle's CAN Bus actually transmits. Engine hours, proprietary fault codes, and driver behaviour parameters live in OEM-specific PGN ranges. Ankh maintains reverse-engineered decode libraries for major North American and European truck OEMs — updated as OEM firmware changes message formats.
ELD Compliance from the Technical Specification, Not the Certificate
FMCSA certification confirms a device passed the initial test suite — it says nothing about co-driver HOS edge cases, personal conveyance exception handling, or the CMV synchronisation tolerances that DOT officers test at roadside inspections. We implement from the Technical Specification, not the certificate.
Automotive EMC from the First Prototype, Not the Compliance Campaign
A commercial vehicle generates more EMI than almost any industrial environment: 150V load dump transients on a 24V system, starter motor inrush, VFD switching, and broadband ignition noise into the GHz range. We design to ISO 7637-2 and CISPR 25 from the first schematic — not after a failed compliance campaign when PCB changes are expensive.
Fleet Platform Integration Built into the Firmware
Samsara, Geotab, Verizon Connect, and Trimble each have specific device registration flows, data formats, and authentication requirements. We implement platform integration at the firmware level during development — so data arrives in the fleet manager's existing dashboard on day one of deployment, not after a separate middleware project.
