The WSDA-RGD (with internal GX3 inertial sensor) is configured to produce the following messages on startup.

GPS Data (1 Hz):

  • UTC Time
  • LLH Position
  • NED Velocity

AHRS Data (100 Hz):

  • Euler Angles

From this output the WSDA logs:

GPS (1 Hz):

  • latitude
  • longitude
  • height above ellipsoid
  • height above MSL
  • horizontal accuracy
  • vertical accuracy
  • speed

AHRS (100 Hz):

  • roll
  • pitch
  • yaw

The WSDA-RGD does not log any data until it gets a valid time, if it is set to get time from GPS only it will not log any output from the GX3 until the UTC timestamp from the GX3 is valid, even though the GX3 is producing valid AHRS data.

This data is not user configurable and is not available as a live stream through LiveConnect.

All LORD MicroStrain wireless sensor nodes, wireless base stations, and wireless sensor data aggregators are shipped from the factory with their radio frequency set to channel 15 (2.425 GHz).

This channel setting was established during 2012.

Previously all wireless products were set to channel 25 (2.475 GHz).

If you are mixing new nodes and base stations with older nodes and base stations, please be cognizant of these different channel settings.

The Node Discovery function of Node Commander will help you sort out which nodes are on what channels; Node Discovery is channel independent and allows the base station to communicate with any node, no matter what channel it is on

Sampling methods such as synchronized sampling, low duty cycle, network broadcast, etc. require that all nodes are on the same frequency so you will want to insure that you have adjusted the channels settings of the nodes to suit.
