Before the Test

The sponsor will provide the following:
 

Formal letter to the FGCS Secretariat requesting the test (8-10 weeks before the test date.)  Be sure to explain why a new FGCS test is required.  Include a brochure or list of features (especially new advancements) and accuracy specifications for new equipment.

Proposal for observation schedule (dates/times, session lengths, and stations observed.) See the FGCS web site for a recommended observation schedule.  FGCS may modify the proposed schedule as necessary.

Point-of-Contact information (name, phone, e-mail) for project planning.

List of other civilian personnel involved, with names, SSNs, and nationalities  (for station access passes.)

FGCS will provide the following:

Approval for the test, with a planned observing scenario.

Arrangements for access to stations located on government facilities.

---

During the Test

The sponsor will provide the following:

Five sets (plus spares) of calibrated GPS equipment: receiver, antenna, tripod (fixed-height tripods are recommended,) power supply, psychrometer, barometer, observer, and vehicle.

Data downloading and processing facilities.

FGCS will provide the following:
 

On-site personnel to monitor field operations and data processing.

Calibrated fixed-height tripods, psychrometers, and barometers for loan, if any are available.

To-reach station descriptions and static and kinematic observation field logs.

Observed CORS GPS data in RINEX2 format.

Precise GPS satellite ephemerides in SP3 format.

---

Data Deliverables

The sponsor will provide the following:

Software- Two copies, with keys and documentation.

Project Report- Summary of activities and results.

Data Files (produced separately for each survey mode tested:)

Field Logs-  Completed originals, reviewed for accuracy and clarity, with any problems highlighted.

Raw Data-  All raw data files, in receiver format and RINEX2 format.

Ancillary Data-  e.g. precise ephemerides files, if used. Provide source information for any ancillary data.

Processed Data-  All significant processing input and output files.

Bluebook Data-  A-File, B-File, and G-File for all observed baselines.

Optional Data- If desired for comparison, produce the following station and baseline information:

Coordinate Data-  (e.g., Adjusted latitudes, longitudes, and ellipsoidal &/or orthometric heights with accuracy estimates)

Baseline Data-  (e.g., Length, azimuth, Northing,  Easting, and Up distances, with accuracy estimates)

Any other significant positional parameters available.

FGCS will provide the following:
 

Preliminary analysis of the survey data.

FGCS letter stating preliminary findings.

Reprocessing of RINEX data with NGS software.

Detailed analysis of the survey data.

FGCS report stating detailed findings.

---

Processing Guidelines

Baselines are defined as mark to mark, not antenna to antenna, except for CORS stations.

Produce bluebook files for all of the observed baselines. (For a session with n stations observed, # baselines = (n*(n-1))/2)

The following (optional) additions to the sponsor's report are recommended:

Coordinates from a minimally constrained adjustment of static data (hold station GORF fixed)

Coordinates from a constrained adjustment of static data (hold GORF, ASTW, and ATHY fixed)

Loop closure analysis and comparison of repeated baselines.

Comparison of bluebook and coordinate data with FGCS standards.

---

Public Meeting

At the end of the test, the sponsor and FGCS will present their preliminary results at a public meeting held at NGS headquarters in Silver Spring, Maryland.  Contact the FGCS Test coordinator with space and audiovisual requirements.
