Why the Ailunce H1 DMR radio has powerful GPS capabilities

Ailunce H1 DMR (Digital Mobile Radio) is an advanced handheld communication device designed to provide reliable GPS tracking and ranging capabilities. By supporting GPS L1C/A, SBAS L1C/A, QZSS L1C/A and BDS B1I navigation systems, the H1 DMR radio ensures high-precision positioning in different environments around the world. The high-precision positioning capabilities make it an ideal choice for emergency response, outdoor adventures, search and rescue teams, and team operations that require real-time location sharing.

Ailunce H1 DMR radio with powerful GPS function

Dual-Mode Navigation Support

GPS + BDS Compatibility: The H1 dmr radio supports both the Global Positioning System (GPS) and the Beidou Satellite Navigation System (BDS). GPS has 24 satellites for global coverage, precise timing, and widespread use, while BDS has 30+ satellites for global coverage and strong expansion capabilities. This dual-mode design enhances the signal availability of H1 radios, especially in urban canyons or remote areas with limited satellite visibility.

Multi-constellation augmentation: Additional signals from SBAS (Satellite-Based Augmentation System) and QZSS (Quasi-Zenith Satellite System) increase the accuracy and reliability of positioning information, so the H1 DMR radio can achieve positioning accuracy within 3-5 meters under optimal conditions.

Real-Time Location Tracking

After turning on GPS on the H1 dmr handheld device, you can directly obtain the current latitude and longitude, speed through the device interface, and support real-time location tracking.

Distance Measurement

The dual-mode GPS ranging function of the Ailunce H1 DMR radio enables users to maintain accurate spatial awareness in dynamic environments, which is very suitable for tactical navigation or rendezvous planning, effectively improving team safety, and is very suitable for high-mobility tasks such as search and rescue or wildfire fighting. Real-time team member position distance updates prevent disorientation.

Manual mode: In the H1 digital channel, the user can request the GPS coordinates of a contact from the address book. The device calculates and displays the relative distance and bearing between the two parties.

Automatic ranging: After turning on the automatic ranging of the Ailunce H1 dmr amateur radio, the h1 will automatically check the distance of the contact every 10 seconds to continuously monitor the location of team members in outdoor dynamic scenarios such as search and rescue missions.

Out-of-range Alarms

The overrange alarm function of the Ailunce H1 DMR digital radio prevents team members from accidentally straying from the activity area, thereby ensuring the safety of the team

Reference Point Calibration: Set a reference location (e.g., a base camp or incident site) to activate Out-of-Range Alerts.

Threshold Configuration: Customize distance thresholds (e.g., 500 meters). If the device moves beyond this range, it triggers audible and visual alarms to prevent team separation .

Power-On Self-Test

Turn on the power-on self-check function of the Ailunce H1 dmr radios. During the startup process, the H1 will automatically perform a GPS health check to ensure the normal operation of the GPS function during use.

Technical Highlights

Low power design: Ailunce H1 dmr radio’s optimized GPS module ensures longer battery life, supporting 24/7 operation even with frequent location updates.

Cross-brand compatibility: H1 dmr digital radio works seamlessly with DMR Tier I/II networks, enabling interoperability with other DMR radios.
