Darsat
Darsat is a system that uses space-time curvature to determine the distance (ranging), direction (azimuth and elevation angles), mass, and radial velocity of objects relative to the site. The word is an initialism compiled from the words detection and ranging, space and time.
All objects impact space-time curvature (STC). Darsat systems detect an object's impact on local STC.
"Darsat" refers to two two types of technology: passive darsat means reading the ambient curvatures of nearby space-time, while active darsat involve sending a "ping" and measuring STC fluctuations generated by that ping. Passive darsat is undetectable.
Darsat to Realspace (DTR)
Darsat is capable of measuring gravitational signatures in realspace when the site is in Membrane Beta.
Signal Strength
Cross-membrane signal strength and reliability varies greatly, and is influenced by unknown factors. Signal strength is measured on a six-point relative scale of reliability:
- Very Strong
- Strong
- Moderate
- Weak
- Very Weak
- None
Range
Cross-membrane detection maximum range is 400 kilometers, but range varies based on unknown factors.
Excerpts
From SHAKEDOWN: Corporal Kanya Saetang checked her station’s displays. DARSAT—Detection and Ranging, Space and Time—measured gravitational imprints in a sphere radiating out from Keeling to an effective range of 10,000 kilometers, with another 5,000 kilometers of semi-effective range beyond that. While darsat could make an active ping, it was currently in passive mode, reading the ambient curvatures of nearby space-time.

From SHAKEDOWN: According to Lincoln, sometimes darsat worked while in-dim, sometimes not. Hasik said the Mud produced some kind of variable interference, but he had no idea what it was or how to counter it. Lincoln compared it to flying a terrestrial aircraft through a storm of jammers, except you didn’t know what a jammer was. Hasik had a simpler analogy: he called darsat-to-realspace detection “temperamental.”
