Receivers and the YOLOL code that will use their value get executed in a random order within a single YOLOL tic, meaning sometimes YOLOL may compute before receiver updates or it after it updates twice depending on how they happened to be ordered. To accomodate this in a brute-force way, the system enforces that readings from all 9 receivers agree with each other whether they are all delayed, or over ticced or all proper.
The following line checks whether all receivers pointing to a particular Origin Transmitter (like East) show values within a particular tolerance based on their seperation inside the core. If they do, a flag is set to 1. This is repeated times for each set of 3 transmitters pointing to the same transmitter (Front, Center and Up Points)
fd=abs(:F1S-:O1S) ud=abs(:U1S-:O1S) i=(fd<2.5)*(ud<2.5) :Chk1=iThe values from the receivers are allowed to pass for further processing only if all checks on all 9 transmitters report a GO.
if :Chk1*:Chk2*:Chk3 then :O1=:O1S :F1=:F1S :U1=:U1S end goto1Whether this has happened successfully is reported on the status light :Nav.
:Nav=:Chk1*:Chk2*:Chk3 goto1In an ideal environment where we are provided distances to a particular location (transmitters) in a cheat like manner such that there is no travel-time for the signal or doppler effects like in StarBase, you only need 3 points to uniquely determine the position of a ship with 1 caveat: it is not possible to determine which side of the origin circle (towards the planet or the belt) you are without having a 4th measurement. However, in practical cases it is only necessary to determine which side of the plane the ship resides once (and not individually for each set of receivers).
The system is designed to use the minimum number of receivers possible without changing signal target, grouped in the smallest packing possible so that it can fit almost any ship. For this you need exactly 10 receivers. 3 for Center Point 3 for Front 3 for Up 1 for Mirror Plane disambiguation
