Chinese company FOIF is offering a new survey receiver, the A50. FOIF said that with the A50, the company focused on developing a smart design for a receiver to make it lightweight, yet powerful, making it easy to use for fieldwork. Besides Bluetooth, wireless radio, and mobile network (2G and 3G), Wi-Fi feature was added to broaden data communications for GNSS. The A50 is designed to provide excellent performance, with a high-sensitivity GNSS module.
According to FOIF, the A50 has not only sophisticated onboard software, but also optional application programs such as FOIF FieldGenius and Carlson SurvCE, providing multiple field solutions.
The A50’s features include:
- Wi-Fi to achieve quick and long distance parameters settings and data transferring;
- Tracking of GPS, GLONASS, Galileo, BeiDou satellites on 220 channels;
- An industry-standard GNSS engine (Trimble, NovAtel) that can access local CORS;
- horizontal real-time accuracy (rms) of 10mm+1ppm, and vertical of 20mm+1ppm;
- OLED display with superior brightness and temperature range
- Rugged design, with an IP67 rating;
- Voice messaging.

To many variables here. So which is it: a Trimble board that is 220 channels or a NovaTel board? Is it 8mm or 10mm horizontal? Did they write FieldGenius or is that done by MicroSurvey?
Looks like I’ll need to flip my readers upside down in an attempt to read the worlds smallest display.
Doesn’t sound like they know what they are doing with this press release or possibly their products.
