PRODUCT DESCRIPTION

BZGNSS BZ-251 GPS with Built-in Compass - Optimized for Long Range

The BZ-251 is our professional-grade all-in-one GPS+Compass module designed for pilots who demand maximum reliability, especially for long-range FPV and fixed-wing applications. The 25×25×8mm form factor accommodates a larger high-gain ceramic antenna for significantly improved signal reception compared to mini GPS modules, while still maintaining a compact footprint and light weight.

Equipped with our latest customized high-performance chip and new generation integrated signal amplifier, the BZ-251 delivers industry-leading satellite acquisition speeds and rock-solid tracking. With the ability to lock onto 50+ satellites across all major global navigation constellations, you get consistent <2 meter accuracy whether you're flying in open fields, dense urban environments, or along forest edges.

Larger High-Gain Ceramic Antenna

The 25mm size allows for a bigger, more sensitive ceramic antenna that outperforms smaller mini GPS modules:

Stronger Signal Reception: Higher gain for improved satellite tracking at low elevation angles
Better Penetration: More reliable positioning in challenging environments
Long Range Optimized: Maintains solid lock even at extended distances
Stable Tracking: Fewer satellite dropouts during aggressive maneuvers
Faster Acquisition: Larger antenna contributes to faster TTFF times

Built-in High Precision Compass

The integrated factory-calibrated magnetometer provides rock-solid heading data:

No Drift Performance: Stable heading even during long flights and temperature changes
Accurate RTH Direction: Precise return-to-home heading calculation even in strong winds
Wind Drift Resistance: Combined GPS+compass data enables superior wind compensation
Heading Hold Mode: Stable course lock for fixed-wing navigation
Interference Optimized: Compass placement carefully designed to minimize magnetic interference from onboard electronics

Blazing Fast Satellite Acquisition

Never wait for GPS lock again:

Cold Start: Under 35 seconds from power on to full 3D fix
Hot Start: Under 1 second when almanac data is available
Signal Reacquisition: Instant lock recovery after temporary signal blockage
High Update Rate: 10Hz position updates for smooth, responsive flight control

️ Professional Grade Anti-Interference

The BZ-251 features our most comprehensive interference protection:

Built-in Metal EMI Shielding: Completely isolates GPS/compass circuitry from flight controller noise

Optimized PCB Layout: Careful component placement and grounding minimizes internal noise

New Generation Signal Amplifier: Actively boosts weak satellite signals

Power Supply Filtering: Additional LC filtering for clean operation even with noisy BECs

Magnetic Isolation: Compass positioned away from high-current circuits to reduce deviation

VTX/ESC Resistant: Proven to maintain lock even with high-power video transmitters nearby

Full Feature Set for Safe Flying

The integrated GPS+Compass enables all advanced flight modes:

Precision Return-to-Home: Accurate navigation with correct heading back to launch
Rock-Solid Position Hold: Stable hover for aerial photography and surveying
Failsafe Rescue: Reliable position+heading for emergency failsafe activation
Long Range Confidence: Consistent tracking for multi-kilometer flights
Wind Resistance: Superior wind drift compensation
Waypoint Missions: Full autonomous waypoint navigation in INAV/ArduPilot
Cruise Control: Heading hold for relaxed fixed-wing flying
