Skitterdoc 2077

Right. But has she done that yet? Or is she having to move before hand?
1) Trying to stay in LA to finish your education, risking being kidnapped by a corp who will use you as leverage on a friend.

or

2) Relocating to Night City, where you will closer to family and will be able to continue your education. And, there'll be a PMC who will try and keep you safe.

Yeah, I may be missing some of the nuances, but...
 
I'm about half done with the next chapter, but I have been down with an ear infection for the past week. Had to take almost the entire week off from work, not because I was ill per se but because flying with an ear infection is not a good idea. I'm better and able to hear out of that ear again now, though, so yay.

However, it is time for my annual recurrent training at work so I will be gone for a week for classroom and simulator time. I don't need to study that much, as I always do well in the simulator, so I will try to get some writing done while in the hotel room, as there won't be much else to do.

Sorry to hear about that, hope you get better.

P.S. Sorry for the joke.
 
I think a good way to track a Taylor body would be to implant some high quality accelerometers and do some dead reckoning. As long as the relative positions would be kept in sync with something like GPS normally, in case of a disappearance the accelerometer data could be used to calculate the position of the kidnapped body. It's not the most precise, but it'd be undetectable, untraceable and unblockable with the Haywire-tech.

Yeah, my goto solution to that problem would also be realtime kinematics: the sensor fusion of GNSS, inertial measurements, and other environmental sensors (typically barometers, compass, magnetometer, etc.)

TBH, I'm surprised there is no IMU (inertial measurement unit) built into any of her implants, it's a cheap way to increase positioning accuracy and availability in urban areas: receiving signals when in a "canyon" formed by tall buildings is hard, because only a tiny strip of sky is visible and multipath signal propagation due to reflection off the buildings
... though maybe there already is, and her Tinker powers does not cover using her implanted sensors for PNT?
For context: IRL, every(?) smartphone already includes an IMU, though I'm unsure whether they all do sensor fusion with GNSS.

I thought about whether corporations would ensure this is not included (at least in widely-available cyberware) but I don't see the potential motivation. As black bag jobs already involve jamming or some other way of disabling the victim's communications. the victim's knowledge of the location is then unimportant unless either:
- The target (or their cyberware) survives and escapes from their captors after being taken to a corporate lab or some other identifying location, i.e. not a random warehouse. Presumably, they'd learn of their location during the escape, if not earlier... assuming escape is at all possible.
- The target is expected to use covert communication that the team cannot block and those channels can't readily be used to find the victim. by radiolocation or the Haywire trilateration Taylor was considering. Presumably, someone with such extensive countermeasures implanted wouldn't be stopped by the lack of IMUs in commonly-available gear.

Moreover, such channels (or merely expectations they are possible) would change everything about operational security; Dr. Hasumi couldn't just waltz into Arasaka's labs, for one.
TL;DR: I think it's safe to assume Taylor's ansible is Out Of Context, and corporations wouldn't have a strategic interest in restricting access to implanted IMUs.

That said, there still is a decent motivator for Taylor to build a way to find her Haywire pairs: inertial navigation is subject to integration errors, so the precision degrades as time goes by without access to a position reference (like GNSS, hypothetical Haywire trilateration, or just going past a well-known location)
The combination of both would provide high-precision in the short term, and bounded error during longer "trips."

Disclaimer: I work on precision positioning & timing systems for fun (and for work now, kind of)
... to the point I apparently made an account on SV just to blather on about it xD

Yikes, I hope you feel better soonest... and looking forward to more Skitterdoc. <3



Right. But has she done that yet? Or is she having to move before hand?

IIRC, there was something about her completing the paramedic course, and working in the same hospital now so it will be easier to get a similar position back in Night City.

In principle, she could give her notice and GTFO immediately. Might not be the best to get references, though Dr. Hasumi being an MD (at the same hospital?) may smooth things over.

On the flip side, I don't see what incentives a kidnapper would have, with Dr. Hasumi in Arasaka's hands.

Does inertial navigation work off-planet when dealing with orbits?
Yeah, and that's one of the reasons NASA is making deep space atomic clocks.

Current-gen spacecraft rely on 2-way communication with Earth for positioning, through the Deep Space Network's antennas, and that account for a large chunk of the DSN's time budget.

In the story's context though, things get pretty interesting: Taylor doesn't need a super-precise clock in each body, because she has a direct and constant link to her "cyberdeck in the cloud," which could host one time standard for all bodies, or "a few" for redundancy; long-term, I'd assume she may maintain a couple location with Haywire pairs, a compute cluster, and (possibly) precision clocks, say one in Night City and one in the O'Neil (micro)cylinder.

As SpiraSpira pointed out in-story, the existence of her ansible fucks with General Relativity, so the actual implementation depends on how they decide physics work: if the Haywire signals are subject to relativistic Doppler, I believe (offhand, without doing the math) they could be used as-is; otherwise, a correction would be needed to convert reference signals between the inertial frame(s) on Earth and in-orbit.



It should work for measuring accelerations to feed into an orbital modeler. OTOH, any inaccuracies would compound over time since last real navigational fix...

Normally in orbit you have easy access to astronomical position fixes, though.

It indeed suffers from similar integration error issues as on Earth. And yes, in space astronavigation usually works, though GNSS signals are usually available in Earth's orbit.

While all this talk of measuring your position with an advance GPS system in space is great, its been going on for a while. So ill put in my own two cents.

In space I'm sure that they have devices aimed at planets. With the radioactive decay of planets\ gas giants\ sun\ black holes Cores to work off you should get plenty if data to triangulate position and speed. As the object movies it can measure that output and the speed or delay as the signals decay.

From there you get into increasingly more advance and finicky measurement systems. Ad nauseam.

Radioactive decay sounds pretty useless here? Reflected sunlight is the easiest way to spot most Solar System bodies. Not sure what the second best is, I would guess thermal IR.

I was also confused with the mention of radioactive decay 😅

That sounds about right to me, though I'm no astronavigation specialist.
I'd expect reflected sunlight to have a nice bonus: the same sensor might also detect other stars, which would work for conventional astronavigation.


I think Apollo used inertial reckoning with astronomic fixes to navigate, though idk what level of navigational precision was required.
The Apollo missions indeed used a sextan to get position, velocity, and attitude, with the PGNCS providing the IMU and integration.

More recently, the SR-71 "Blackbird" had an automated astro-inertial navigation system.


In-story and in-orbit, I think "plain old astronavigation" would make sense because it can be done just with Taylor's eyes... and I would assume there's already a Kiroshi-compatible app for it ;3

I've worked on telco location services, there are indeed integrations between different location methods. This is why your phone can be located even if it has no GPS/GNSS transceiver, but these mostly rely on the mobile towers (using signal strength, timing and direction to locate you).

Does inertial navigation work off-planet when dealing with orbits?

It should, unless relativistic effects come into play and even then they might be compensated for. Plus the space station on which Taylor #3 is probably has a known orbit and she'd only need to determine her relative position to the station.

Thanks! I knew phones can provide location without GNSS, but I didn't know whether that was a "dumb" fallback mechanism, or proper sensor fusion to get something better than each individual method.

Yeah, there are multiple fall-backs, I guess in a tech-heavy world like Cyberpunk 2077 with a lot of the Internet still in shambles there'd probably be some other way to locate stuff, but probably all of them can be jammed. Taylor is in a unique position that she has a method safe from interference and interception and nobody even knows she has these, so she's easily underestimated, which should serve her in the future (as it has previously).

If Taylor has some quite good magnetic sensors (maybe several micro arrays?) then she might be able to gain information most people don't expect her to have? The patterns of changing magnetic fields, near Earth, and across the Solar System, with local effects from things like metals, and moving charges, might also prove useful [DATA] for shard-chan, particularly if exploitable for cybernetic purposes...

Navigation might be only the start of what she could do...
