Local Positioning System Puns

The key element for the MVIS investor is to be found in Figure 1, #44 light emitting diodes…

I have several beams positioned in several different directions and I'm trying to determine moments and torsion on each element - however I'm struggling a bit how to place my local axes on each beam? Is there a rule to follow when doing this?

Hello! I'm looking for some ideas for my indoor positioning system project.

I already have read quite a lot about many different methods of measuring the distance, trilateration etc.

But I'm still not sure what's the best way to go about it. RSSI measurement is probably the easiest, but it's quite inaccurate...

Are you familiar with projects similar to this? I'd really appreciate any suggestions and help.

GPS with civvy static isn't exact enough to wall off your yard so a robotic lawnmower will stay in range. What is the industry standard way of plotting off your lawn so a robotic lawnmower stays in your yard and doesn't wander into the road? I would think numeric stakes that send out a pulse could possibly planted in a geometric shape with the lawnmower knowing to stay on the side of the line it is already on.

I'm just not sure if people already do this or what?

I love home automation. I have an ISY and use insteon products (motion, water and door sensors, plugs, etc) thoughout the house along with cameras here and there.

Is there a way to build a "GPS" for my home? I am looking to be able to tell who is in what room and such. I know there are a few options. Motion detection is just not cutting it... sitting down or sleeping is an obvious downfall. I looked into beacons but not sure if those are good or become cumbersome with knowing who is in what room or have issues with triangulating. Any suggestions?

Hey everybody! Probably this is a simple or commonly posted question... though I can't find any help online, nor do I find the location in the scripts for my problem, but as shown in the image below, my sprites are too low.

I've tried to fix it using the debug menu, which makes everything look ok, but as soon as I go in battle, it goe s back to the positioning issue (see second image)

Anybody know how to fix this issue?

Kind regards!

Is there any platform/system or even method for controlling lights,fans,etc... based on the user's location indoors? I've researched indoor tracking methods but haven't found any application for smart home as stated in the title. What I want to be able to do is to track my position by any indoor tracking method an link that to any smart home platform...

My theory starts with the idea that a sequence of road sections, when sampled over a distance (let’s call this “x”) is made up of a unique sequence of curves with unique properties (Radius etc). Even “straight” sections of road have a curvature (which tends to infinity).

Stitching together these unique sections of road, you can assign every section of road a “fingerprint”. This information would be stored in a database.

The idea is that using computer vision and lane detection, you can readily detect the curvature of sections of road as you drive. Many self driving car projects use this tech to determine how close to the centre-line the vehicle is.

Comparing the collected sequence of “curvature” of the road against the database in real-time, should allow you to pinpoint the location of the vehicle on earth. As you drive, the location becomes more precise.

Hi there,

Newb question here.

I recently rewatched the excellent Band of Brothers mini serie on WWII, and viewing currently Path of Glory on WWI. They both reminded me a question i have everytime i see somebody ordering artillery fire on some location.

They use very concise positioning system that seem too easy to be true (it's said on the radio directly from the combat field under the bombs), really short (a few numbers like "32, 58, 78"), and not precise (not lat/lon). I wonder then how does the system work, how people can guess the opponent'position while being attacked, what's the precision, is it the same between WWI/WWII/now...

Thanks for your lights.

I wanted to share with you an absolute positioning system I figured out for the Sky-Watcher Star Adventurer popular tracking mount. It works kinda like a GOTO because you can point at any point in the sky without doing any start hopping, using a red dot finder or anything like this albeit it's not computerized lika a true GOTO.

I know this will help me save countless hours in the field trying to zero in on deep sky objects especially with long focal lengths which is by far probably the most frustrating part of shooting with a simple tracking mount like this.

Here's the link to my video about it: https://youtu.be/tNPIMKOB9k4

##Korea Positioning System

The Korea Aerospace Research Institute (KARI) had planned to, by 2035, launch seven new satellites into orbit for an independent Korea Positioning System (KPS), free from North Korean interference. Though the issue of North Korean jamming doesn't exist any longer, the Collapse and with the... issues that the Triumvirate Republic of America - who owns the GPS command center - is facing, KARI deems it necessary to speed up the KPS to be operational by 2030.

The initial planned satellites - three into geosynchronous orbit and four into inclined geosynchronous orbit - will be launched from the Naro Space Center by 2030. This will, as initially planned, provide independent navigation and positioning signals within a 1,000 km radius of Seoul.

However, the expanded plan will be to launch seven more satellites every two years, up until a total of 28 satellites in 2036. Additional satellites will fly in Medium Earth Orbit to provide broader, global coverage to users of KPS.

In addition, the planned Korean Augmentation Satellite System (KASS) program will go forward as detailed, increasing GPS (and, come 2030, KPS) accuracy.

A budget of $3 billion will be granted to achieve this timeline.

Anyone see feasibility in this??
