On the Devices tab I only have ‘Internal GPS’ available and due to the limitations of Windows 10 and Windows Location Services, Internal GPS is only initialising when WiFi is connected (not very handy when you are out in the bush with no connectivity).
However, other applications allow me connect directly to COM1 and access the NMEA data stream which works perfectly fine with no connectivity (this particular tablet has a dedicated GPS chip).
Is there a way I can add a device or force Avenza to use COM1 (9600 baud rate)?December 27, 2017 at 10:27 am #6797
Thank you for your post. To connect to an external GPS on Windows 10, there is a two-step process. The first step is to ensure that your device itself registers that an external GPS is connected to it. The second step is to open Avenza Maps, go to Settings > GPS and refresh the list until the GPS unit is displayed. Once it is displayed, please select it as the GPS to use. Please note that we have only tested a handful of GPS brands/models, and as such cannot guarantee that all GPS devices will work with Avenza Maps. If you continue to have any problems or have any other questions please let us know.

I have am using a Avenza 3.4.0 on a Galaxy Tab S2, and trying to get the Trimble Catalyst DA1 Antenna to work with Avenza, with little success.
You mention above that you need to go into settings>gps to see a list of GPS units. GPS units never appeared when we had the Catalyst connected using the correct apps and set up on the Galaxy.
Is there a way we can get the catalyst to work with Avenza?

In general, if the GPS unit will work with the device, Avenza Maps will use it as well. We have only tested with Garmin and Bad Elf GPS receivers, so we know they work, but cannot guarantee that any others work. The steps provided above were for the Windows version of the app which allows users to select the GPS receiver to use inside of Avenza Maps. Unfortunately, this behaviour is for Windows only, and on Android and iOS platforms, there is no way to specify the GPS receiver to use.

After my initial post I gave up on the idea of using the tablets internal GPS and have had great success with using Avenza with a Trimble R1 Bluetooth receiver. It works perfectly fine after pairing with the Trimble app and shows up in the device list.
In your reply to i.scott you mentioned compatibility with Garmin receivers. Do you know if the Garmin GPS 18x USB receiver (https://buy.garmin.com/en-AU/AU/p/27594) is supported? The only reason I ask is because the USB model can only output data in Garmin proprietary format where as the DB-9 pin serial connector version outputs data in NMEA 0183 format (industry standard) or proprietary Garmin format.

In general we do support Garmin devices, however, as technology changes, there is always the possibility that something internal has changed with the Garmin receivers or specific models. In general we test with the Bluetooth models, not USB models, so I cannot say with any certainty whether that specific model would work or not.November 7, 2018 at 4:11 pm #16241
I’m trying to easily get better accuracy in remote locations using an iPhone and Avenza Pro. My office has an old bluetooth enabled GPS Pathfinder Pro with a VGA port and a software CD–but my laptop supports neither. David, you mentioned connecting to an antennae via Trimble app, which app and would it work for my situation? If not, I’m happy to buy a different antennae but need recommendations on simple and effective options. Thanks for any help you send my way.November 8, 2018 at 5:09 pm #16257
Thank you for your blog post. We currently support GPS receivers built by Garmin and Bad Elf.
Other brands may or may not work and thus if you purchase one we can not guarantee you will be able to use it with Avenza Maps.

I am wondering if any progress has been made to specify the GPS receiver to use within the Avenza application with an Android tablet. I am working with a Samsung Galaxy Tab S and looking to purchase an external GPS receiver that will pair via bluetooth to my device.
I understand that I can “enable mock locations” for the Avenza applications and adjust the settings to “keep all fixes,” but I am still unsure how I will be certain that Avenza is in fact using my external GPS reciever as opposed to the internal (built-in) gps.
The reason I need an external GPS is the project I am working with requires sub-meter accuracy.December 19, 2018 at 1:28 pm #17028
There isn’t currently a way to specify the GPS receiver that is used within Avenza Maps on an Android or iOS device. As long as you have an external GPS unit that is compatible with the application, like a Garmin or Bad Elf GPS receiver, and it is configured to the vendor’s standards, it will be utilized in the app. The best way to be sure of this is to do some testing in the app with the device while connected and disconnected to the external GPS.

Would you happen to know of a Garmin or Bad Elf GPS receiver that can provide sub-meter accuracy?
I am familiar with the:
Trimble R1 ( < 1 meter accuracy )
Bad Elf Surveyor ( ~ 1-meter stationary accuracy with SBAS+PPP )
Geneq ISXBlue II ( 60 cm; 95% real-time with SBAS corrections )
this is where I am getting the info for these recievers from:
https://www.anatumfieldsolutions.com/Bluetooth-GPSGNSS-For-Mobile-GIS-Field-Tested-and-Compared_b_38.htmlDecember 20, 2018 at 1:16 pm #17046
I can’t confirm that any deliver sub-meter accuracy. The Surveyor is Bad Elf’s best option in terms of their Bluetooth GPS receivers which delivers ~1-meter positioning. Of the Garmin devices that I’m aware of, none of them advertise sub-meter accuracy. I recommend reaching out to Garmin with your inquiry as they can provide a more thorough response.
Please let me know if I can assist you further.
All the best,
