Your charge rate acceptance number is surprising to me, I've never seen anything like this in my years of experience designing EV batteries. Preconditioning helps extreme fast charging but isn't necessary for 1-2 C charges at all unless it's very cold out.
There's some caveats to this depending on the exact chemistry but if anything the newer semi solid state NMC cells are even less dependent on this and can charge down to -20C.
I work on bare metal embedded systems though, so maybe there's some nuance when working with bigger OS libs?
The relative direction of the acceleration would be "up". This is what she means.
On March 11, 2024, NextNav announced it signed an agreement to acquire spectrum licenses covering an additional 4 MHz in the lower 900 MHz band (902-928) from Telesaurus Holdings GB LLC, and Skybridge Spectrum Foundation. NextNav acquired the additional spectrum licenses for a total purchase price of up to $50 million, paid for through a combination of cash and NextNav common stock. The acquired licenses are in the same lower 900 MHz band as NextNav's current licensed spectrum. On April 16, 2024, NextNav filed a rulemaking petition with the Federal Communications Commission to deliver a spectrum solution in the Lower 900 MHz band to facilitate a terrestrial positioning, navigation, and timing network (as a complement and backup to GPS) and broadband.
If they're actually able to "sync" (again a poorly defined term) given the problems associated with network latency and different hardware it would border on magic.
Also a lot of notes in the schematics/layout as well, utilizing layers. Overall I'm pretty satisfied.
