Description
JMHH Inc 1 – Assured PNT for Today’s Battlefield
The JMHH Inc 1 is an affordable, M-Code GPS-enabled handheld designed to deliver assured position, navigation, and timing (A-PNT) for the dismounted warfighter. Developed under the JMHH Joint Program of Record, it is smaller, more efficient, and more secure than legacy military solutions, while offering a more intuitive, modular, and cost-effective alternative to current industry offerings.
By integrating M-Code GPS with advanced commercial technologies — including a ruggedized touchscreen, inertial measurement units (IMUs), software fusion engines, and an innovative antenna design — the JMHH Inc 1 provides a defense-ready product built for mission success in the most challenging environments.
Fully ATAK-enabled, the JMHH Inc 1 seamlessly exchanges data with WinTAK for mapping, mission planning, intelligence, and other operational needs. This compatibility ensures it fits effortlessly into the broader ecosystem of digital tools supporting today’s military operations.
Key Features:
-Touchscreen and button interface for flexible control
-Auxiliary ultra-low power, quick-access display
-Small form factor (134mm x 81mm x 29mm) and lightweight design (320g)
-Hot-swappable AA batteries with 19+ hours of life at –20°C
-Enhanced user interface and user experience (UI/UX)
Key Attributes:
Multi-Constellation, Any Sky Capability: Supports CA, Y, and M-Code; L1/L2 GPS; Galileo, QZSS, BeiDou, and GLONASS
Operational Endurance: Four AA lithium batteries provide over 19 hours of continuous operation, with hot-swappable capability for uninterrupted missions
Navigation Resilience: 6-axis IMU, 3-axis magnetometer, barometer, and data fusion for GPS-denied environments
Mission-Ready: Purpose-built for anti-access/area denial environments and aligned with modern military operational architectures
TAG serves as the prime contractor for the JMHH under the U.S. Space Force, Space Systems Command, as part of the Military GPS User Equipment (MGUE) Increment 2 program — delivering a next-generation, assured PNT solution for the warfighter.
