GNSS Format Descriptions
Motivation
GNSS data sets follow a well defined set of standards. These standard formats provide many advantages, the most obvious being it is easy to exchange. ASCII and binary formats both satisfy this function, but ASCII does it with greater generality because binary formats are computer operating system dependent. These formats have evolved to satisfy growing requirements, satellite systems, capabilities, etc.
But reading a standard format description is a tough task. This section aims to provide the community a reliable and powerful tool which explains these necessary standards in a very easy and friendly way, aided with explanatory tooltips. These tooltips will be triggered automatically when the mouse is hovered over a field. These explanations include the standard description of the field, the format in which is written and, if applicable, its units.
Get familiar with the different format standard(s) involved in the GNSS data sets, take your time to analyse in detail particularities and characteristics of the GNSS systems, observables, versions, models through the different data sets provided. Please email any suggestions, comments or requests to us.
