If you also make an educated guess at target range, the you can get a good first approximation of speed.
All measurements can then be refined after you begin actively tracking the target.
The fourth bearing, which should provide range and speed has never worked for me.
If you have vector math and trigonometry skills, you could probably solve it mathematically. I have created spreadsheets on my ipad that substitute for my missing crew.

The problems with four beaing is that they are difficult for convoys or task forces since the brings can be mistaken from the whole lengh of the sonvoy itsefl. Besides it can take some very long times to get a wie sprea of angles and the target is changing course pretty often in RSRD campaign. Thanks for the avise.
