The Axis That Never Stops: Slip Rings, Line Count and Service Life
Continuous rotation is a single line on a datasheet and a design decision that reaches into power, video, maintenance intervals and the shape of the search pattern.
How Much Stabilisation Do You Actually Need?
Stabilisation is usually specified by copying a number from a competitor. It can be derived instead, from the field of view of the sensor and the motion of the platform it sits on.
From Bearing and Range to a Grid Reference: the Target Location Error Budget
A sensor reports an angle and a range. Someone else has to act on a position. This paper assembles the error budget between the two and shows which term dominates at which range.
Accuracy, Repeatability and Resolution Are Not the Same Number
Three specifications on every positioner datasheet get used as though they were interchangeable. They are not, and the difference decides whether a system points where you told it to.
Owning the Subsystem — Why Localisation Changes What a Buyer Can Ask For
Localisation is usually discussed as supply-chain risk. The more consequential effect is technical - what a buyer is allowed to change, and how quickly, when the supplier owns the design rather than resells it.
MIL-STD-810G — What a Qualification Claim Does and Does Not Prove
"Qualified to MIL-STD-810G" is an incomplete sentence. This paper explains what the standard is, why the method, procedure and severity matter more than the number, and how to compare two suppliers who both claim it.
What a Line-of-Sight Stabilisation Figure Actually Costs
A stabilisation specification is not one number but an error budget assembled from bearings, encoders, gyros and control bandwidth. This paper takes the budget apart and shows where each order of magnitude is bought.
