Using Point One Navigation with Flex and Flex Mini

Using Point One Navigation with Flex and Flex Mini

Getting Started

Point One Navigation (P1N) services provide ubiquitous access to Real Time Kinematics (RTK) throughout the continental United States. P1N services require no configuration and may be used with any phone or tablet running the Bad Elf Flex app.

To examine coverage in your area of operation, see our coverage map. 
 
The following Flex/Flex mini configurations allow use with a P1N trial or paid subscription.
  1. Flex Standard - with an active Flex token
  2. Flex Extreme
  3. Flex Mini Extreme
Note, subscriptions and trials of P1N services are directly tied to a specific Flex/Flex Mini serial number. Each Flex/Flex Mini requires a unique subscription.

Activating P1N Services


To start P1N services on your Flex or Flex Mini
  1. Open the Flex App on your phone or tablet
  2. From the opening application screen select the option "Correction Mode"
  3. From the Correction Mode screen tap on Point One Navigation

Note, the current correction utilized by your receiver is highlighted

If there is no active subscription, you are presented with the option to:
  1. Start a free trial or,
  2. Purchase a subscription

If you have an active subscription, your Flex app will verify the receiver you are connected to, capability of using P1N services, and connection to the internet. You must have internet connectivity for P1N services either via WiFi or cellular connection.

The section labeled "Connection to Point One network" indicates:

  1. Free trial or paid subscription including an expiration date
  2. The distance to the nearest corrections station
  3. Current GNSS fix type

To connect to P1N services, click the blue button labeled "Connect". Once the connection occurs, the field below indicates corrections are flowing and highlights with a green checkbox.

The Flex/Flex Mini status section indicates if your receiver is actively using the corrections provided by P1N.

Note, the ideal distance for best results is less than 20km from the nearest station. As your distance from the nearest station increases, accuracy will decrease. The reliability, and accuracy, of a position with the nearest station beyond 100km may be significantly diminished.

When you first establish a connection, the GNSS operating mode switches from 3D/SBAS to RTK (FLOAT). In this mode of operation, your receiver is working to produce a reliable position. Float positions may have some variance and will have highly variable accuracies.

Note, when your receiver switches from 3D/SBAS to RTK you will incur a datum shift from ITRF08 to NAD83. This datum shift may amount to 1-2 meters in positional location and should be addressed by the software application used for recording.

When the GNSS operating mode switches from RTK (FLOAT) to RTK (FIXED), your receiver has achieved its most accurate position as indicated by the accuracy on the main screen. Fixed positions have little variance once established.

Note, when your receiver remains in NAD83 during the transition from RTK (FLOAT) to RTK (FIXED)

Tapping on the "< Back" button on the top left of your screen returns you to the Corrections screen. The Point One Navigation item is highlighted confirming your receiver is actively using RTK services from P1N.
