GNSS Surveyor - Centimeter Level of Accuracy

App features:

- Easy to use one touch previously configured commands to communicate directly with GNSS Bluetooth device.
- Display location information and quality of the position data in real-time with sub-meter/ Centimeter accuracy
Receive GPS status data like position, height, accuracy, satellites, velocity, etc.
- You can forward RTK correction data to your high accuracy external device. RTCM data is loaded from the internet by the internal NTRIP client.
- View all or hide all constellations individually on sky plot and distinct color for different constellations for better identification.
- Constellation information for GPS, GLONASS, GALILEO, BEIDOU, QZSS, SBAS SATELLITES.
- Send commands to external GPS device and view the output data on Terminal.
- Log all received NMEA messages and BINARY DATA on Terminal window.
- Built-in NTRIP client to access RTK or DGNSS correction from any RTK Network.
- Direct IP feature for RTK corrections data.
- Convert degrees decimal minutes to decimal degrees and vice versa
- Configurable audible and visual alerts.
- Multi language support.
- Multi measurement units support.

How it works?

Connect external bluetooth GNSS device with GNSS Surveyor and compare your location with different satellite systems. It provides advanced information such as HRMS, VRMS, 3D RMS values, HDOP, PDOP, VDOP, Differential GPS. Satellites in view.

Easy to allow mock location on your android phone or tablet and use the position of the external receiver in any 3rd party application. Get GPS status data like position, height, accuracy, satellites, and speed in real time. View and analyse the position information provided by the GNSS receivers and metadata related to its location.

Paid Features Available:

- NTRIP (Network Transport of RTCM data over IP)
- Record NMEA (Real time position information understand and expect data to be in NMEA format)
- Macros
- Terminal

The following information are displayed:

- Lattitude and longitude
- Altitude
- Speed or pace
- Bearing
- UTC time
- Satellite data (optional)

GNSS precision to the next level, such as:
- Global Coverage
- Centimeter Level Accuracy
- Fast TTFF
- Multi-constellation and multi-band
- Highest security

I would love to see this work to provide 2cm accuracy as advertised. I have not seen it work on Samsung S21 ultra (Android 11). Tech support said they are addressing that. Has anyone gotten this to work on a S21? Does this require a separate bluetooth GNSS receiver to achieve 2cm accuracy? If it can not achieve 2cm accuracy with the newest smartphones, what is the benefit, as there are many apps out there already working. Thanks

I don't see where the "surveyor" part of GNSS Surveyor is... storing points, measuring between points, laying out points, lines, arcs, distance to lines, cut/fill to point or DTM... Am I missing something? The only thing I see is that it will connect to a GNSS unit and show/store the position from NMEA output.

It does not work under Huawei 10 Android 7. First, cant use already Bluetooth device connected and paired (U-blox in my case), next will not run offline. Next, need active internet connection. Probably will have problems on other phones also.

Doesn't work. Bought it for the NTRIP client. Will not download mount point list. w ok nt even lock on to satellite with internal gps.

If you write down lat long on paper you can plot it on map. It was off by about 3 meters. 300cm. Don't know what else you could do with it.

My GPS is a BLE system and not BT. Your app cannot connect to it. Could you add BLE support in the future?

Eri. .. Oct 3, 2020     

I can not find even the simplest description how I can get this app to work. What Bluetooth device do I need? A simple intro would be nice

Nik. A. Nov 2, 2019     

Hi, could you please advice on a proper budget bluetooth receiver that works with your app? Also what diff corrections provider you recommend?

Looking good, just asking me to buy , macros and record NMEA to work properly, someone know use with Geo-Fennel RTK? let me try to set up with Geo fennel FGS1. i don't know if work.

Does what it says....helped in my traditional way is survey, but how much I can/should rely on this is yet to be tested...anyways great app:)
