I have a client that is looking for someone to write him some software that takes multiple files that have been collected by some commercial software called Maglog from Geometrics in the USA, merges them, displays them graphically for on screen editing and sorting etc. 

Maglog creates files, both asci and binary as required, from instruments recording the data. It time stamps them with PC time on every record.

 

We have a positioning/navigation system that is running separately also recording the position and elevation plus some other information we require. This only has GPS time within the data stream and is not linked to Maglog.

 

So once we have merged the Maglog files with PC time we need to merge it with this file. Accuracy is paramount.

 

The way we currently do that is one of the channels recording in Maglog is a stand alone gps which we log with all the other instruments. This has the gps time in the data string.

In other words we are recording this gps for no other purpose except to get the gpstime that is common with the PC time. The record is stamped with both.  We then merge this with the navigation system using the gpstime.

Anyone interested can inbox me and I will send the client details. He will obviously pay for your time.

My brother does something similar. Send me your contact details and I'll ask him to get back to you.
