Dear friends, I would like to introduce you the RTKite GNSS RTK L1+L2 module receiver.
http://northsurveying.com/index.php/instruments/gnss-rtk-receiver
Designed specifically for Pro and Semi-pro UAV, Robotics and Industrial applications, it connects directly to the Pixhawk and other autopilots and is specific for millimetric Photogrammetry, LIDAR Scans, Themography, etc.
The RTKite is a full Receiver (not a basic GNSS board) with an internal OS that can connect directly to standard CORS stations with its embedded GSM/GPRS cellular modem, can be configured and operated by Bluetooth, COM or TTL communications and can be set with our freeware for Android, Windows PC or WindCE or Linux, or even with text string commands.
It also can receive and transmit RTCM or CRM correction signals by UHF radio or our unique AutoCaster system that allows direct link connection by the integrated mobile modem with an stable transmission range of 75Km on Fixed position.
In is in fact a miniaturization of our professional surveying RTK receiver SmaRTK, (first generation released on 2012), and is compatible with our unique AutoCaster system for direct Base to Rover cellular data link.
Below, an Autocaster test on a modified DJI drone with Pixhawk and the RTKite GNSS with the lightweight helical antenna.

@Emin Bu.
Just want to bring to your attention that the RTKite is a professional Double Frequency (L1+L2) military-grade GNSS RTK receiver, and we offer lifetime service and free customization and personal integration support.
"Low cost" doesn't mean "cheap", it means that, compared to simmilar specifications it is below its target price. For perspective, since the model introduction 6 months ago, the receiver is already in its 3rd hardware generation and 15th software generation, and integrated in more than 10 different types of industries, no just UAVs.
If you are looking for "cheap" RTK solutions, I recommend you to look for Single Frequency (L1) systems, that can fit the purpose of testing but cannot perform on the conditions that our aerospace customers need, that is real time, within seconds, all the time, in non-optimal environments.
Low cost???
" The Receiver with antenna has a price of $ 2,300.00 a pack of battery charger, charger and USB Cable Usd$ 300.00, and the UHF Radio Modem Module Usd$ 400.00, plus the dispatch from Barcelona. If you like more details please write to: Emea@Northgps.Com"

@andru88 Very good!
It would be interesting if you make post of integrations for the community to understand better how RTK systems work, it would help everyone.
@andru88, indeed we don't use Novatel. We are professional GNSS RTK producers with 10 years on the RTK market.
We supply directly to integrators and representatives, and yes, it is low cost compared with the main players of the GNSS market.
The RTKite receiver is integrated now not only in UAVs but in robotics, precision agriculture, machine control and other industries, however we are making it available to the Semi-Pro integrators as well.
If you need any datasheet we have everything publicly available: www.northsurveying.com
It is called OEM-V Form factor, and defines the location of drill holes:
20 pin is a format set by Novatel and used by many brands for compatibility, including North:

@andru88,
thank you.
It looks like market is full of L1 + L2 GNSS RTK receivers.
What is a price ?
@Darius, Now I get your meaning of "2D navigation" however that is only on the frontend towards non-professional users. Internally there is no other navigation than 3D, for the reasons I've already exposed.
A point that has not been mentioned and probably is the origin of the confusion is the hysteresis or "gauss-smooth" that consumer grade receivers do, to avoid people to think their receiver are jumping 3m in 1 second. This is done by the Ublox, Garmins, etc., and we have reviewed that is being done on the 3DR L1 receiver as well. In RTK this is not used and the position are always raw from the RTK solver.
Regarding your CORS project, of course we do supply CORS receivers and fixed or choke-ring antennas. There are two main ways, one is the classical Server+NTRIP software+Receiver or our AutoCaster, that does not need a server or NTRIP but connects direct to the said CORS receiver by mobile network or fixed IP.
Regarding legislation, as far as you do not use radio broadcast, and use only internet, there is nothing to ask permission for.
The Autocaster system is free and do not uses passwords, so has free access for IP broadcast and is the simplest way to set it up and running in 5 minutes. You can use an NTRIP software but it is not needed for 1 base standalone. What do you loose? Potential VRS, but if you ever need that you could always switch.
Please write to emea@northgps.com to have an access to the detailed list.
Good day Darius
I will gladly provide you a unit.
I have setup a CORS system in Namibia as there is no CORS system there. My brother is a professional land surveyor there. Initially we it was for our own use but we have given everyone access to the system.
What I did was to use point to multi point cellular routers, the local cellular service provider created an APN for us and provided us with static IP addresses for the routers.
Unlike the local CORS system that has been down for the last 4 days preventing from logging data and posting it here the system in Namobia has been up for just over 3 years with zero downtime.
I will let you know exactly what is happening after my meeting with the university tomorrow.
They are looking at producing the units as well as further development of the units.
Regards
Anton
@Bernardo,
thank you for your excellent input.
What I mean by 2D navigation is GPS car navigation,
2D GPS marine navigation.
What I mean by 3D GPS navigation is drone flying in 3D space.
I would like to set up first Open CORS (open to the public) GNSS RTK reference station,
public funded personally.
Could you deliver your L1/L2 RTK receiver/transmitter kit + antenna
and at what cost ?
@Anton,
could you deliver your L1 RTK receiver/transmitter kit with antenna to set up
Open CORS reference station, public CORS station providing open, unrestricted access 24h on the private ground ?
If you are aware of EU legislation to control operation, set up of such Open CORS GPS RTK reference station, please let me know.
I am interested to develop Open CORS stations at Open FabLab.
Just free, open access, no registration since RTK GPS corrections on open IP brodcast channel.

The EPN real-time GNSS data streams can be downloaded from the EPN regional broadcasters using a free Ntrip client software (available for several platforms).
Each broadcaster will request that you first complete a user registration to grant you the authorization (user-ID and password) to access the EPN streams they provide: User registration for ASI (Italy), BKG (Germany) and ROB (Belgium). Click here to have an overview of the streams presently available from each broadcaster and here for some station operation details generated by the BKG broadcaster.
