LMV will replace the Land Rover and Pinzgauer in nine variant roles built on a Common Base Platform; GPV, BFA, TMV, UV, EPV, C2V, ESV, TCV and MSV. For that to work, power, data and HUMS need to be shared platform services rather than fitted separately to each vehicle.
GAViN products are vehicle mounted LRUs that take the same 24V platform supply and publish the same GVA topics, scaling by role. A general purpose vehicle can run PDU2000 plus HUMS. An equipment support or utility variant adds INV3000. A troop-carrying or tactical mobility variant adds IPU400 for soldier systems. The architecture stays the same across every role.
The LMV PSQ scores suppliers on their technical ability to deliver a digitised, GVA compliant platform. Threshold items are an essential condition covering power, EMC, interconnect and monitoring. Objective items are the additional capabilities positions a Joint Force node ahead of a standard utility truck, that include HUMS visibility, 230V sustainment power and power/data that runs from mounted to dismounted.
On-systems are a UK power partner. Our products are already in production form factor, the ICDs are released and there’s a path to variant specific packs without redesigning the electrical systems of the vehicle.
Each GAViN unit is a sealed, face-mounted LRU with a DEF STAN 23-009 interconnect, 24V vehicle input and a GVA Ethernet/HUMS path. Data sheets for each product are available to download below.
The primary 24V PDU (Power Distribution Unit). It accepts a DEF STAN 61-5 Part 6 platform supply and feeds six protected 23-009 outlets for mission systems, weapons, sensors and communications.
A vehicle-mounted inverter for cabin, workshop, mission-system and sustainment loads. It gives an isolated 50Hz output with GVA/HUMS telemetry over Ethernet.
The Intelligent Infantry Power Unit. It charges and synchronises dismounted soldier systems from the platform’s 24V supply and bridges USB (Universal Serial Bus) to DDS across the mounted-to-dismounted boundary.
A CAN-to-DDS Health and Usage Monitoring gateway. It accepts ISO 11898/MilCAN vehicle bus traffic, maps it onto the DEF STAN 23-009 information model and publishes OMG DDS topics for crew stations, mission systems and platform HUMS.
The table below maps the GAViN suite to the power, interconnect, EMC, HUMS and soldier integration themes scored in the LMV PSQ. Threshold means conditions of participation or a must meet requirement. Objective means a scored differentiator or stretch goal. Question IDs should always be checked against the PSQ Guidance on the Sourcing Portal.
Every GAViN LRU accepts a conditioned 24V vehicle inlet on a 23-009 or small D38999 circular connector, with an operating range of 18-32V DC. Interlock and sense pins are provided on the power ICDs.
GVA circulars are used on both the power and data faces. Ethernet is published as 1000BASE-T and the HUMS gateway publishes the 23-009 model as OMG DDS topics, so crew, mission and logistics consumers share one bus.
PDU2000, INV3000 and HUMS are specified to Land Class A. Isolated CAN, galvanic AC isolation and sealed LRU construction all support the platform’s EMC design.
Six front-face 23-009 outlets, each rated at 10A, for 2000W aggregate. OCP, OVP and OTP are independent per outlet, so a fault on a single outlet is contained and the node stays live for the rest of the platform.
One Ethernet/DDS path runs from the power products and the CAN gateway. Legacy J1939, MilCAN and CANopen traffic is translated rather than hardwired into each variant’s harness.
HUMS timestamps health, usage, hours and fault state and forwards them to the platform HUMS service, with a local circular store kept through comms outages. INV3000 and PDU2000 report load, temperature, hours and faults over GVA Ethernet.
The unit gives 3000W at 13A, isolated pure sine, 50Hz +/-0.1Hz with THD (Total Harmonic Distortion) below 3%. Two operator face outlets, specified at order as MIL-DTL-38999 or BS 1363. Protected by UVLO, OCP, OVP, OTP and short circuit foldback.
Four 100W USB-C PD ports plus four Nett Warrior connectors, for EUD charging and vehicle synchronisation. A USB to DDS bridge keeps soldier systems on the information model.
Compact sealed cubes and finned LRUs: HUMS at 0.45kg and 110 x 70 x 75mm; IPU400 at 200 x 100 x 100mm; PDU2000 at 62mm high; INV3000 at 4.8kg. Corner hole or face screw mounting, with captive caps.
Designed and manufactured in Letchworth, Hertfordshire. A common ICD language and released drawings ahead of cable manufacture make On-systems a UK SME partner for primes needing UK workshare.
Mobility and troop roles. Start with PDU2000 for protected 24V outlets and HUMS for the digital bus. Add IPU400 where infantry sections mount and dismount with Nett Warrior or EUD loads.
Command and mission system roles. PDU2000 plus HUMS give clean distribution and a single DDS view of platform state. INV3000 covers 230V radios, docking and on the move workstations where specified.
Utility, equipment support and ambulance roles. INV3000 supplies isolated 230V for tools, medical and workshop loads. PDU2000 keeps mission and vehicle services on supervised 24V rails.
