Product Description
Foif A90 Base +Rover+Handbook+GPS pole+Antenna GPS RTK Measurement System GNSS
Foif A90 Base +Rover+Handbook+GPS pole+Antenna GPS RTK Measurement System GNSS1. Satellite channel upgrade
Support up to 800 channels of multi-satellite systems: China Beidou BDS, EU Galileo Galileo, US GPS, Russia GLONASS, India IRNSS, Japan Qzss, and SBAS satellite augmentation system, and supports multiple civilian bands of each satellite system. It allows you to continue to work under a variety of complex terrain conditions, dense occlusion and harsh electromagnetic interference environments, and provides accurate and reliable positioning solutions.
Support satellite band: GPS: L1CA/L1C/L2C/L2P/L5
GLONASS: L1CA/L2C/L2P/L3/L5
BeiDou:B1/B2/B3
Galileo:E1/E5/AltBOC/E5a/E5b/E6
IRNSS5: L5
SBAS: L1/L5
QZSS: L1CA/L1C/ L2C/L5/L6
2. Data link upgrade
The built-in full Netcom 4G network module supports one-to-many operation of self-built network base station FOIFNET, and supports the private card private network CORS network of different communication service providers in various provinces, allowing you to obtain more stable and reliable network signals in urban and rural areas and surrounding areas.
The built-in high-sensitivity transceiver integrated radio allows you to receive clearer and more stable differential signals in harsh mountain conditions, and can easily set up base stations within a working range of 2-5 kilometers, making it easier for you to use. At the same time, it supports a variety of common international and domestic protocols, which is convenient for joint operation with other RTK equipment.
Network module parameters: GSM: 900/1800MHzTD-SCDMA: B34/B39TDD LTE: B38/B39/B40/B41; CDMA 1x/EVDO: BC0WCDMA: B1FDD LTE: B1/B3/B8
Radio module parameters: power 0-2W typical operating distance 2-5KM (depending on the environment) frequency 410-470MHz; communication protocol: PCC-EOT, TrimTalk 450S, TrimMark III, South, GeoTalk, GeoMark, etc.
3. Richer functions:
The hardware in the machine adopts ARM architecture and integrates the Linux operating system. Users can not only directly access the WEB control interface embedded in the control host through the mobile phone wifi, but also control the host to set the working mode, download the measurement data, upgrade the host program, manage the host registration authority, etc. , so that users have a more convenient way to control the A90 when it is inconvenient.
The host also supports the dual storage function of measurement data, which can synchronously backup data to the host memory when the user collects data to prevent accidental loss, and can set the cloud storage function to backup the measurement data in the server cloud, so that unexpected situations are nowhere to be done.
4. The new Android software also brings a lot of surprising changes to users:
Support SHP, DXF, EXCEL, DAT, thinking, Daoheng and other data formats to export, better compatibility with common software on PC, and support more powerful graphics engine, support SHP, DXF, JPG, TIF, IMP and other vector data to map 1G raster image processing time is 3 minutes and can be compressed to less than 40M losslessly. At the same time, it has rich layer display management functions such as layer order, visibility, element style, etc. It is faster and can be used more convenient.
5. Sufficient power and memory:
The 3400mAh×2 batteries also ensure the normal use of the instrument for one day. When the power is insufficient, the batteries on both sides can be replaced in turn to ensure the uninterrupted operation of the instrument. At the same time, the F58 handbook battery is exactly the same as the A90 handbook battery and can be used interchangeably to avoid the trouble of insufficient power.
In order to meet the needs of data storage backup and static data preservation, the host has onboard 8G large-capacity memory, and supports TF card expansion of 32G memory, which can fully meet the needs of long-term measurement work.
