Product Introduction
1. Military-Grade Extreme Environment Protection
Passes 3-axis 200Hz vibration and 50G shock tests (15-minute frequency sweep), IP67 waterproofing, and -40°C to 85°C temperature range, meeting the GJB 150A-2009 military standard requirements for missile carriers, armored vehicles, and more.
2. 40dB Ultra-Strong Signal Enhancement
Dual-stage filtering architecture (pre-filter + IF filter) with 50dB out-of-band attenuation (±50MHz) ensures positioning error of less than 0.5 meters in areas with strong interference, such as 5G base stations and radar stations, achieving a fivefold improvement in accuracy compared to conventional antennas.
3. Nanoscale Miniaturization
At 25×25×6mm, this antenna is one of the world's smallest GNSS antennas (58% smaller than its previous generation), designed for demanding applications such as surgical robot positioning, police drones, and aerospace payloads.
4. Wide-voltage intelligent power supply
2.7-10V ultra-wide voltage input (power consumption <25mA), supports seamless switching from vehicle cold start (9V) to battery power supply (3V), and voltage fluctuation tolerance reaches ±300%.
5. Industrial-grade electromagnetic protection
15kV air discharge ESD protection + full metal shielding cavity, solves the risk of electrostatic breakdown in medical equipment/substation scenarios, and extends the life to 100,000 hours.
Application scenarios
National defense and military industry: individual positioning system, armored vehicle navigation terminal
Precision medicine: surgical navigation robot, mobile CT positioning
Aerospace: rocket-borne positioning, satellite payload communication
Energy infrastructure: substation inspection robot, oil pipeline monitoring
Intelligent transportation: high-speed rail black box, autonomous driving perception redundancy
FAQ
Q: Will 40dB gain self-oscillate?
A: The dual filter architecture suppresses feedback, out-of-band suppression>50dB, and there is no self-excitation in actual measurement (refer to IEC 62138 standard)
Q: What is the significance of the axial ratio 4dB@90°?
A: Ensure signal stability at large inclination angles (low satellite elevation angles), and improve positioning availability in high-rise areas by 70%
Q: How to start with 2.7V low voltage?
A: Built-in low-voltage startup chip (-40℃/2.7V startup current <5mA) to solve the problem of vehicle cold start
Q: What are the advantages of TNC connectors over SMA?
A: Thread locking vibration resistance is improved by 3 times (vibration 200Hz vs SMA 50Hz), suitable for helicopters/excavators
Q: How to achieve 15kV ESD?
A: Antenna substrate integrates TVS array (response time <1ns), in line with IEC 61000-4-2 Level 4
Q: Can 6mm thickness be embedded in a metal casing?
A: Must be external! It is recommended to use nano-absorbing materials (optional ANT-ABS01) to isolate metal interference
