Audited Supplier The magnesium aluminum alloy shell makes the A90 more robust and reliable, while the intensive design makes the A90 easier and more convenient. The internal structure of A90 has been improved more. The whole circuit of A90 adopts full socket connection, and there is no wiring cable inside, so as to eliminate the quality problems caused by loose cable. The internal partition board is processed by CNC, which improves the internal heat dissipation, signal shielding and structural stability of A90, so that the a90 is not only better used, but also more durable. Support star chain endurance and China precision.
Product Features
1. High performance four in one antenna: GNSS antenna/Bluetooth/WiFi/4G all network communication module highly integrated.
2. Internal spacecraft structure design: RF and microwave form an independent loop, perfectly solving internal signal crosstalk, ensuring that the receiver always obtains optimal data accuracy and maintains the strongest anti-interference performance.
3. Up to 1408 channel motherboard: full galaxy tracking, support for Beidou-3 satellite, support for star chain endurance and station differential technology.
4. Linux+Cortex second-generation intelligent system platform, providing users with efficient computing and unlimited expansion of product functions
5. Built in integrated transceiver radio station: 0.5-2W adjustable, supporting various transmission protocols, operating distance up to 5 kilometers
6. Removable dual lithium battery design, with a battery capacity of up to 6800mAh, allowing for battery replacement when the host is constantly powered on
7. Large capacity memory: built-in 8G, expandable 32G;
8. Triple data insurance: RTK collects data in a manual and saves it synchronously with the host, uploads backups on the cloud server, and has zero risk of accidental loss of measurement data.
