The only missing thing is the speed but we have so many easy way to get that... you can do a full job by doing both observation 3min15sec apart or you can also use the periscope technique (which is the fastest method but the less accurate too).

Afaik there are four ways:

The periscope method you mentioned
The 3.15 which is convenient but very inaccurate at distances
The Nomograph method wich is great for long intervals
The Hydrophone table method, which is always great as a second opinion
(table thanks to Grayrider and Raduz, you rock!)

I always use a combination of these, except the first, which I yet have to try.
