It’s really cool when your mapping app displays the estimated accuracy of the GNSS receiver you are using. Conversely, there’s nothing more frustrating than your mapping app showing a GNSS estimated accuracy that is wrong . Unfortunately, the latter is quite common. The problem is that you likely don’t know that your mapping app is giving you bogus GNSS accuracy values.
This is one of the most common questions we get at Eos: “Why is my mobile device mis-representing my receiver’s accuracy. The glitch lies in a miscommunication between the device itself and the receiver’s actual accuracy. In this article, Eos explains how to derive the true accuracy of any GNSS receiver you use.
Get the full explanation for why your receiver might be “lying” to you. Read the full feature article answering this question from the April 2017 Eos newsletter.
Al’s Corner – Technical Tips
Hi… My name is Alvaro and I am the Technical Support Manager at Eos Positioning Systems. I am inviting you to visit our Learning Center on our web site for useful technical information, how-to’sand video tutorials. This section will be updated regularly with new material. Any question? please do not hesitate to contact our technical support center.
For our users who have not done so yet, I am inviting you to update your Arrow 100 GNSS receiver’s firmware to take advantage of the new Galileo constellation. Please fill out the support contact form with at least one Arrow 100 serial number to receive the firmware update instructions.
For our European users, make note of last month’s EGNOS PRN changes(see the “Eos Latest News” below). No action is required as your Arrow receiver will track and use the new PRN #123 automatically.
For North American users of WAAS, please note that PRN #133 is currently not broadcasting ranging information but only SBAS corrections. PRN #135 and #138 still provide ranging and are used by your Arrow receiver as “extra” GPS satellites for positioning.
