UPDATE: After a brutal day in 100 degree (real F degrees) , full sun and clear sky in a thick swamp, I was surprised and confused to discover the data points I collected were a mix of DGPS, RTK float, and RTK Fix. I'm not sure how this happened since there was absolutely no indication that the decryption keys were loaded, armed or active. Probably a software bug or just bad sw design. It appears that RTK Fix was only achieved in absolutely unobstructed view of clear sky. The slightest tree cover drops it down to RTK float or DGPS. RTK Fix errors were 1.5"H/3"V, RTK float errors were 4"H/8"V, and DGPS errors were 2'H/4'V. Bottom line: This unit is great for wetlands delineation, but nothing less than RTK fix will do for topographic surveys and even that may not suffice for fussy construction work. When the subscription for the L-Band service runs out, I'll probably be buying a companion Facet Surveyor to use as a base station. Maybe even sooner. Overall, Sparkfun has made quite an impressive and useful, cost effective unit. And while their software and documentation are heads above the competition, there's room for some improvement - they are 95% there. As far as customer support, lets just say there's an opportunity there for them to exploit.
Thanks a million for the feedback. This is quite a turn off. Glad you could test out how well it performs in a real world and I admit it's quite unfortunate. I wonder how well Hemisphere's Atlas compares to this tho. I also think that 1.5''H/3'' errors are certainly great but not quite there yet... Although you can't expect more from a cheap GNSS chip like the F9P.
very very very tempting product! Sparkfun delivers once again... I honestly think that Base-less GNSS surveying is the future. Nonetheless, many questions remain unanswered. 1- Is this going to incur any subscription fee to continue receiving those corrections? If yes, how much? 2- What correction service is being used here? 3- Hemisphere has a similar service they call Atlas. Theoretically it has worldwide coverage already so I'm very curious if there are any plans to get this cover a global scale later.
I'm not interested in this l-band corrections service (ntrip will do just fine). But i am interested in the 'upgraded' antenna. Does this one have any benefits over the regular Facet? L-band corrections are nice in areas without mobile internet, but that's no issue where i live. If it has no benefits whatsoever i could save the cash on the regular model.
No there's no radio here. It has 2 pieces of ICs on the same PCB so there is no radio. It's basically an all-in-one solution One is a classical GNSS receiver chip like the F9P and the other is yet another ublox chip that receives the L-Band corrections and feeds them back to the F9P chip to account for the corrections. Another example is Hemisphere's Atlas. You can google it for more info.
Came for the ZED, stayed for the corrections. Nice product!

Thanks for the lo-down, hopefully things can improve over time; as for now you've helped me make my decision.

Great to see Nate after a long time. Looks like he was in his den cooking something interesting. Wish to see him often.
your link is wrong, it goes to the original facet not the SparkFun RTK Facet L-Band
love the product ❤️❤️❤️
Estare pendiente para comprarlo cuando haya servicio en Mexico City
Awesome product. So this won't work without a base in South Africa, correct?
Hi newby question - will this device work in UK and is it certified for use in UK? thanks

Ok can I used it at Ensenada Baja California México is near San Diego ... And have u put tild angle mode
So how long until this amazing product will be available in Australia ?
amazing!!
Impressive! 👍
Incredible!!❤

Does it have tilted position of minimum 45 degrees... Regards
Is L-Band available in asia? Special in the Philippines?
I am in Canada. Does this mean L band won’t work here?
I want it! But PPP its only available on USA and Europe :c
How would you connect this to one of the old school Trimble GeoXT instead of SW maps? I'm a bit confused
This product already have a built in radio to comunicate whit other unit?

WOW!
VENHA PARA O BRAZIL ???
Qual valor do aparelho?👍
Is like the gnss terminator
You should do a video of products that are under $500, if that's possible.
They do? Regularly? What on earth are you complaining about? Stop wasting bandwidth.
the price is too much ,not slightly , it's basically more than twice the price of facet without L band.
