I recently acquired a daylight lamp through a reward program from my health insurer. It is the Beurer TL100 Daylight therapy lamp, it has bluetooth and can be controlled by the Beurer LightUp app. I have HomeAssistant running at home and naturally wanted to integrate the lamp into my setup, so that I could control it via the Web.

During the development of this integration I used some help from ChatGPT.

RTK uses a fixed base station, ideally you know exactly where it is so that you know the exact location of your mobile unit (else you will at least get a pretty good relative position).

With the new chips, Broadcom, u-blox and others are bringing to market now you are no longer dependend on a base station to get cm-level accuracy. Instead they exploit the different properties of the L1/L5 frequencies to infer stuff about e.g. the atmosphere, as the different frequencies are altered in different ways while travelling to earth[2]. The system can thus reduce its margins of errors[1] in the position calculations. So they are not "interacting" with RTK in any way. The chips are also much cheaper than your quoted $1K price tag.

Disclosure: I work for u-blox, but not an expert in GNSS calculations

Seems like they limit the number of teams you can create [per user] to 101. I guess it's the same dilemma as with domain names again.

While I think it's just a honest overlook by the author (C++17 is just really new), I still think it's funny that a huge portion of the entire article and by extension the argument against variants is rendered moot by RTFM.
