Kroki [1] supports TikZ and by extension: PGF [2] and LaTeX. It supports SVG, PDF, JPEG, and PNG outputs. Rendering is done on the server. URLs can be quite long since the source is embedded in the URL but you can use a URL shortener [3].
Reminds me of Mats Järlström who challenged traffic light timing. "The [Oregon State Board of Examiners for Engineering and Land Surveying] fined Mats $500 and said that he could not talk about traffic lights in public until he obtained a state-issued professional-engineer license."
Regarding deterministic latency, the Time-Sensitive Networking (TSN) [1] set of IEEE standards address this. The IEEE P802.1DG project [2] in particular defines a TSN profile for automotive.
5 meters. However, the "intended target" is not simply defined.
The landing ellipse for Perseverance was 7.7km by 6.6km. The goal is to land at a safe spot within the ellipse rather than land at a specific location.
The new Terrain Relative Navigation capability determines the rovers position relative to the surface during descent by comparing camera images to onboard satellite imagery. On Earth you'd use GPS. No GPS on Mars.
Once the rover knows it's position, it can now determine the safest spot to land using an onboard hazard map. The spot it chose to land at vs the spot it actually landed at was 5 meters apart.
