Do you need a base station for RTK?

Historically, RTK users have been required to setup and maintain their own RTK base station. If you work in an area that offers one, all you need is internet access in the field and a RTK-capable GPS L1/L2 receiver.

What is a RTK base station?

Real-time kinematic positioning (RTK) is the technology for the real time correction the common errors that occur in working with GNSS. A base station usually comes with an internal or external radio or modem to transmit the correction signals. …

How does an RTK base station work?

RTK follows the same general concept, but uses the satellite signal’s carrier wave as its signal, ignoring the information contained within. RTK uses a fixed base station and a rover to reduce the rover’s position error. The base station transmits correction data to the rover.

Is RTK surveying accurate?

RTK GPS Accuracy: What accuracy is RTK? RTK is used for applications that require higher accuracies, such as centimetre-level positioning, up to 1 cm + 1 ppm accuracy.

What is the difference between RTK and DGPS?

So, the difference between RTK and DGPS is that DGPS is the traditional differential GPS. RTK stands for real-time kinematic and commonly uses the RTCM protocol. The traditional DGPS uses an older antiquated protocol while RTK uses a newer algorithm, and the protocol is based on RTCM3.

How do I setup my own RTK base station?

To setup your own RTK base station, you just need three components: 1 RTK GNSS base station receiver. The Arrow Gold and Arrow 200 both have this functionality. 2 RTK base station software. Eos offers the Eos Server software. 3 Simple computer to run the Eos Server software (or you can use Amazon Web Services, or similar, to host the software).

How do I set up a base station?

There are a few ways to set up a base station: a temporary base station is faster but less precise. A static base station takes more time to set up and configure but provides the greatest precision. There is a third option and that is getting your correction data from a public feed.

How do I get RTK correction data?

Paramount to RTK is having access to an RTK Network (a bunch of RTK base stations connected via internet that provide differential corrections) or RTK base station. Fortunately, many government entities (federal, state, local) have setup RTK Networks/RTK bases and make RTK correction data streams available to the public for free or at low cost.

How does a GNSS RTK base work?

The purpose of a GNSS RTK base is to not move. Once you tell a receiver that it is a base station (ie, not moving) it will begin to look at the satellites zooming overhead and calculate its position.
