Set the static position of the receiver.

License: MIT. See license file for more information but you can
basically do whatever you want with this code.
This example shows how to set the static position of a receiver
using an Earth-Centered, Earth-Fixed (ECEF) location. This is the
output from a long (24 hour+) survey-in. Setting the static position
immediately causes the receiver to begin outputting RTCM data (if
enabled), perfect for setting up your own RTCM NTRIP caster or CORS.

Configuring the GNSS to automatically send HPPOSLLH position reports over I2C

SparkFun Electronics
Date: January 3rd, 2019
License: MIT. See license file for more information but you can
basically do whatever you want with this code.
This example shows how to configure the U-Blox GNSS the send navigation reports automatically
and retrieving the latest one via getHPPOSLLH. This eliminates the blocking in getHPPOSLLH while the GNSS
produces a fresh navigation solution at the expense of returning a slighly old solution.
This can be used over serial or over I2C, this example shows the I2C use. With serial the GNSS
simply outputs the UBX_NAV_HPPOSLLH packet. With I2C it queues it into its internal I2C buffer (4KB in
size?) where it can be retrieved in the next I2C poll.

Note: compiles OK with v2.0 but is currently untested
Use ESP32 WiFi to push RTCM data to RTK2Go (caster) as a Server
By: SparkFun Electronics / Nathan Seidle
Date: December 14th, 2020
License: MIT. See license file for more information but you can
basically do whatever you want with this code.
This example shows how to gather RTCM data over I2C and push it to a casting service over WiFi.
It's confusing, but the Arduino is acting as a 'server' to a 'caster'. In this case we will
use RTK2Go.com as our caster because it is free. A rover (car, surveyor stick, etc) can
then connect to RTK2Go as a 'client' and get the RTCM data it needs.
You will need to register your mountpoint here: http://www.rtk2go.com/new-reservation/
(They'll probably block the credentials we include in this example)
To see if your mountpoint is active go here: http://rtk2go.com:2101/
This is a proof of concept. Serving RTCM to a caster over WiFi is useful when you need to
set up a high-precision base station.

u-blox deprecated many -CFG messages and replaced them with new
