Some analysis projects concern a specific set of stations and need to access the coordinates of those stations repeatedly. The GPSTk supports this through a monitor station coordinates (MSC) file. The class MSCStore provides a means of loading files in this format and then obtaining station coordinates based on either strings or numeric identifiers. The format supports discontinuities in station occupations (i.e. moving antennas to new locations) and station drift over long periods due to crustal dynamics.New Format

- These are provided as a convenience for bookkeeping and are not used by the MSCStore class.
- The epoch date is the effective date of the coordinates with no velocity adjustments.
- The earliest effectivity of the coordinates may be earlier than the epoch date.
- Multiple entries for the same station with different effective dates are allowed. The MSCStore.getXVT() method will select the appropriate coordinates based on the effective date.
- For purposes of propagating the station positions, a year is 365.25 days long.
