Depending on which brand of GPS equipment you’re using the file types and therefore file extensions will differ. The reason for this is that the brands each have their proprietary systems with their own file types as opposed to universal ones. For example, have you received files ending in .ttm, .dxf, .csv, .tn3, .ln3, or others and wondered what’s the difference between them?

Are you wondering how a surface model will work with your heavy equipment? Although it can seem complex, it is simpler than you may think. Some machines already come equipped with the technology and others can be retrofitted with aftermarket technology systems. Either way, the most important thing to understand is that they run off GPS.
