Enter your NTRIP Caster credentials and click connect. You will see bytes begin to transfer from your phone to the RTK Express. Within a few seconds, the RTK Express will go from ~300mm accuracy to 14mm. Pretty nifty, no?

What's an NTRIP Caster? In a nutshell, it's a server that is sending out correction data every second. There are thousands of sites around the globe that calculate the perturbations in the ionosphere and troposphere that decrease the accuracy of GNSS accuracy. Once the inaccuracies are known, correction values are encoded into data packets in the RTCM format. You, the user, don't need to know how to decode or deal with RTCM, you simply need to get RTCM from a source within 10km of your location into the RTK Express. The NTRIP client logs into the server (also known as the NTRIP caster) and grabs that data, every second, and sends it over Bluetooth to the RTK Express.

Don't have access to an NTRIP Caster? You can use a 2nd RTK product operating in Base mode to provide the correction data. Checkout [Creating a Permanent Base](https://sparkfun.github.io/SparkFun_RTK_Firmware/permanent_base/). If you're the DIY sort, you can create your own low-cost base station using an ESP32 and a ZED-F9P breakout board. Check out [How to](https://learn.sparkfun.com/tutorials/how-to-build-a-diy-gnss-reference-station) Build a DIY GNSS Reference Station](https://learn.sparkfun.com/tutorials/how-to-build-a-diy-gnss-reference-station). If you'd just like a service, [Syklark](https://www.swiftnav.com/skylark) provides RTCM coverage for $49 a month (as of writing) and is extremely easy to set up and use. Remember, you can always use a 2nd RTK device in *Base* mode to provide RTCM correction data but it will be less accurate than a fixed position caster.

Once you have a full RTK fix you'll notice the location bubble in SW Maps turns green. Just for fun, rock your rover monopole back and forth on a fixed point. You'll see your location accurately reflected in SW Maps. Millimeter location precision is a truly staggering thing.

### SWMaps and iOS
52+
53+
SWMaps is available for iOS [here](https://apps.apple.com/us/app/sw-maps/id6444248083). Please note that Apple products do not support Bluetooth SPP so the Bluetooth protocol on the RTK device needs to be switched from SPP to BLE. More information is available on the [System Menu](https://docs.sparkfun.com/SparkFun_RTK_Firmware/menu_system_status/).

[Field Genius for Android](https://www.microsurvey.com/products/fieldgenius-for-android/) is another good solution, albeit a lot more expensive than free.
