That is correct. However, its last position before pulling the battery will be where it is expected to register again.
If you use your phone in say Lancashire predominantly and then pull the bty and move it to London and then start using it. You might well get a call checking who you are. It's part of the technique used to verify whether a phone has been stolen or not.
My Garmin unit gets down to an uncertainty of about 5 metres, although it seems to be modest about its abilities. Using an OS Explorer map as base reference, it appears to be typically half that. Next time I am passing thruogh Greenwich, I'll really test it out. Sometimes it gets temporarily confused on elevation, the other day on Highgate hill it was convinced that I was below sea level.

is that the NIP should be inadmissible in court because no caution has been issued under the PACE rules.

Speedo inaccuracy allowances are pretty much irelevent for the purpose of the above post since it applies to the drivers perception and not that of the BS.
Radar speed checking systems are regularly calibrated to determine accuracy performance criterion and allowances are applied. Additional allowances added for speedo error give a finite figure above which you are deemed to be speeding.
Determined Speed + Allowance for dertemination method error + speedo error = speed assessed if > than the speed limit in force = speeding if < than the limit in force = not speeding.

Assuming it is bought with cash, and topped up with cash.
The moment a credit/debit card, or cheque, is used, they would be able to trace you.

Police incompetence - not ensuring the form was signed and witnessed. There are a number of errors like this.

It does. Though that positions accuracy is not great it is in terms of time. That is - call from mobile to BS time 1705:30 [some distance travelled] call BS to mobile on last registered Freq - no response. Call from Mobile to BS [another neighbouring BS] time 1707:24. Therefore you can say that in 2 mins and 6 seconds the mobile moved position between cells. Cell range is specific in terms of signal quallity and whichever is the best signal will determine which BS is used where there is an overlap. It is possible to determine on which frequency calls are made and received since frequencies used by adjoining stations must be different, within a predetermined area.
True but you would hardly be speeding over open moorland. It is only relevent where applicable facility to speed in a fairly constant direction, ove time.
On the contrary, you can tell the time the phone was registered, the BS it communicated with, the 2 frequencies used, the number of the phone, the validity of the account, whether the user is black/white or grey listed and a few other items as well. You also fail to take into account that the 'Cell' area of effectiveness with geographical reference is precisely known.
No it wouldn't. Time is irrelevent unles you have either position or speed in addition. [S/D/T]
Triangulation is not required.
The point of the case was that there is a duty to supply the name etc of the driver at the time but nowhere does it say you have to sign the form. There was no question of incompetence or error.
