(II) Positioning Performance
* Signal Coverage: Supports dual-band signal reception of GPS L1 and BD2 B1, with acquisition sensitivity up to -146dBm and
tracking sensitivity as low as -160dBm, enabling accurate capture of weak signals.
* Startup and Response: Cold startup time ≤ 38s, hot startup and re-acquisition time both ≤ 1s, data update rate is 1 time/second
by default, with fast response.
* Positioning Accuracy: Horizontal error ≤ 5m, speed error only 0.1m/s, equipped with 1PPS signal output, meeting high-precision
positioning requirements.
(III) Core Component Characteristics
1. Ceramic Antenna: Adopts a 25×25×4mm ceramic antenna body with a gain of 3±0.5dBi and an axial ratio of 3.0±0.2dB. It receives
signals in a right-hand circular polarization mode, with a characteristic impedance of 50Ω and a VSWR ≤ 2.0, ensuring stable
signal transmission.
2. Amplification Module: Covers frequency bands of 1575.42±2MHz and 1561.098±3MHz, with an amplification gain of 15±2dB and a
noise figure ≤ 2.0. It is powered by 3.0V DC with an operating current ≤ 10mA, effectively enhancing signal strength and
reducing interference.
III. Environmental Adaptability
(I) Operating and Storage Conditions
* Operating Temperature: -40ºC~+85ºC, adaptable to extreme high and low temperature environments;
* Operating Humidity: 95%~100%, capable of stable operation in humid environments;
* Storage Temperature: -45ºC~+85ºC, convenient for long-term storage and transportation.
(II) Environmental Test Performance
It has passed a number of rigorous environmental tests, with stable performance and appearance:
* Low Temperature Test: Placed in -40ºC environment for 12±2 hours, and electrical performance meets standards after returning to
normal temperature;
* High Temperature Test: Placed in +80ºC environment for 12±2 hours, with no appearance damage and normal performance;
* Aging Test: Continuously operated for 12 hours at normal temperature with 5V voltage, showing no significant performance
changes;
* Rain Test: Flushed under a faucet for 4 hours, with no water ingress at the bottom and no impact on electrical performance.
IV. Installation and Lightning Protection Scheme
(I) Installation Recommendations
The antenna features flexible installation and can be deployed on the top of machine rooms, outdoor tops, cable trays, the ground,
or roof poles. If it needs to be installed on a iron tower, it is recommended to be less than 5m above the ground, and the feeder
length should be controlled within 10m to ensure signal reception effect.
(II) Lightning Protection
The insulated lightning protection scheme is recommended, whose core advantage is to reduce the lightning current introduced into
the room and avoid the impact of feeder lightning induction on indoor equipment. The specific requirements are as follows:
* The antenna and feeder must be within the 45° protection range of the lightning rod;
* The routing of the antenna and feeder shall be fully insulated, and the feeder window shall not be grounded;
* An 8kA lightning arrester shall be configured at the equipment port, and no additional lightning arrester is required on the
antenna side.
V. Test Verification
In the satellite reception performance test, the product performed far beyond the basic standards:
* GPS: 10 satellites received (standard ≥ 6), maximum satellite reception strength 48dB (standard ≥ 46dB), and the CN value of ≥
3 satellites ≥ 42;
* Beidou (BD): 11 satellites received, maximum satellite reception strength 45dB;
* Comprehensive Judgment: The satellite reception indicators fully meet the requirements, and the product is qualified.
