Optional integrated U-Blox NEO M8T GNSS receiver
16 Mar 2016
Update 6 March 2020 - Now applies to Mesa 3 as well.
The Mesa 2 can now be purchased with the optional integrated U-Blox NEO M8T receiver, which replaces the standard M8N receiver. This optional receiver offers raw UBX data output for potential further differential correction in real-time (such as over an Internet connection) or post-processed using specific software applications. Such corrections can provide improved location positioning accuracy. For further information, see the following web page.
It is recommended (though not required) that this receiver be used with an external antenna which is connected via the optional antenna connector/pack, such as the Tallysman TW2710 with right-angle MCX connector that we offer.
Accuracy comparison between the standard U-Blox Neo M8N and the optional M8T receivers is as follows.
- Real time SBAS and autonomous accuracy – identical
- M8T is capable of post-processing. M8T post-processing with internal antenna on Archer 2 has been 2 meters down to sub-meter, roughly 60 ~ 90 cm. Use of an external antenna has shown post-processing down to a few decimeters. It is difficult to quantify accurately, as there are many factors to consider; static vs kinematic, baseline length, observable conditions, etc.
