SparkFun RTK Facet vs SparkFun RTK Facet L-Band, no subscriptions - 2.5M or 30cm Accuracy?

GPS/GNSS
1

The $699 RTK FACET in the product overview says - two paragraphs after the Bullet points

Unlike standard grade GPS receivers that have 2500mm accuracy, the accuracy in this mode is approximately 300mm horizontal positional accuracy. and one of the bullets says

  • GNSS Positioning (~30cm accuracy) - also known as ‘Rover’ and note next bullet down says 1.4cm when getting RTK Fix

However product specifications at the bottom say Horizontal accuracy is only 2.5m without RTK implying Meters I believe not 2.5mm or 25mm (they used lower case m) so I am assuming they mean accuracy is 2.5 METERS without RTK.

What level of accuracy have those of you with $699 RTK FACET been able to get without an RTK fix? 2.5 Meters which is not much better than my Apple iPhone 11 which is about +/- 15ft to 30ft

Or did you achieve 30cm (centimeter) accuracy as mentioned in the Bullet Points and paragraphs of description?

Or did they accidently mix up descriptions between RTK Facet and RTK Facet L-Band?

Rover would imply a Base, so I would assume that statement =>
RTK Float ~ 30cm
RTK Fix ~1.4cm

You can also consider the Facet and the Facet L-Band to be equivalent when using the same correction source. The L-Band variant obviously has a built-in method to receive Point Perfect corrections from the Inmarsat satellite, which is 1 of many correction sources available to you.

I consider the Facet L-Band to be an “Easy Button” for certain applications, but it’s just one tool in the toolbox. Your Project/Application Goals (and the location) would dictate the best RTK correction source to use.
