JSNav: An Easy-to-Use GNSS App

JSNav with the earth below

The Archer 2 comes with a new, easy-to-use GNSS app called JSNav, which replaces the older GPS Compass app and includes additional functionality and features. While most of our customers use third-party software to collect their data, JSNav is useful because it gives users a feel for the Archer 2’s GNSS, and can be used to verify satellite reception. It also acts as a useful tool for software development & troubleshooting for our partners. Having said that, JSNav can very well be used to collect GNSS data, if desired. And it does all this in a sleek, user-friendly package.

We wanted to make data storage and retrieval as easy as possible with JSNav, which is why it uses common file types so that you can import and export data simply by dragging and dropping files into the file explorer. This way, you don’t have to deal with cumbersome databases and data conversions.

Here are a few things you can do with JSNav:

Add waypoints

Collect waypoint
Screen for adding waypoints

Record tracks, i.e., map trails

Record tracks screen with JSNav

Make comments on waypoints & tracks

Monitor NMEA sentence & other diagnostic information

Import & export .csv, .kml, and .kmz files to ArcGIS online, GoogleEarth, or other GIS

Navigate back to your collected data points, using the compass feature in JSNav

In designing JSNav, we used Xamarin to facilitate cross-platform functionality, and we used Resco to achieve a cleaner looking user interface. Our hope is that JSNav will provide users with a pleasant GNSS experience and will act as a useful tool for partners from a developmental standpoint.

Give JSNav a try on your Archer 2, and feel free to post any questions or comments below.

    Just bought Archer 2 and whenever I start JSNav and either turn it off in the progran or let it time out it will not go back on without doing a hard reset by holding down the on/off button



    I have a GPS ARCHER 2 with JSNav included but have problems in your settings when I make a geo positioning, with known distances and actual coordinates and the coordinates do not match are presented far from the actual taken.

  3. How can you enter the way points as co-ordinates in UTM WGS84 Zone40 (Northing; Easting; Elecation)

  4. Hi Ankit,

    Thanks for reaching out. Will you please call us at +1-435-753-1881, and we will have one of our experts help you find the best solution. Thank you!

    Can I save multiple tracks as the same name?

  6. I work with Cartesian co-ordinates (X,Y). How do i change the unit from geographical coordinates to cartesian coordinates on JSnav?

    I work with an Archer 2 handheld unit that I have used for several years to collect photo points with ArcPad. I am wondering about using JSNav instead so that I can collect location information with photos on the unit. Is there a way to know the accuracy of the waypoints collected with JSNav? Currently we use EZsurve post processing software with the data we collect with ArcPad to acheive sub meter accuracy. Is there post processing software used with JSNav?

      Hi Janet,

      Thanks for the comment. We’re happy to hear you use the Archer 2. Here’s what you need to know about JSNav: JSNav is a basic tool that shows if an internal GNSS is fully functional. It can change settings and collect basic data waypoints, lines, tracks, and perform simple navigation. It stores estimated horizontal error and point positions, which you can export as a .csv file. However, it’s not a complete data collection app – no tables, points, lines polygons, post-processing, nor projections.

      EZTag CE is a fully featured data collection app. It captures data in various project files, uses predefined features and tables for coding data, and post-processed GNSS data for receivers.
