  2. REFERENCES • ATON POSITIONING MANUAL • ATON ADMIN MANUAL • ATON TECH MANUAL • ATON SEAMANSHIP MANUAL • ATON STRUCTURES MANUAL • SOLAR DESIGN MANUAL

  3. POSITIONINGMANUAL • What is covered? • What is a APR? • Positioning Equipment? Problems? • Positioning terms? • Excursion methods?

  4. What is Covered? • Positioning Instruments and Guidelines • Theory of Positioning • Accuracy Classification for Floating Aids to Navigation • Positioning Methods for Fixed Aids to Navigation • Position Check Evaluations • Aid Positioning Record

  5. TERMS • Accuracy Classification (AC) • Aid Positioning Record (APR) • Watch Circle Radius (WCR) • Assigned Positioning (AP) • Horizontal Dilution of Precision (HDOP) • Most Probable Position (MPP)

  6. Aid Positioning Record • Must be done every time a Floating Aid is visited, or a Fixed Aid is established, rebuilt, or moved • Must be submitted to district within 10 working days or upon return to port • Original stays at unit in Aid File • Original can be destroyed 3 years after Aid is disestablished

  7. CO/OINC must review and sign APR Purpose of CO/OINC signature is to verify: (a) APR complete. (b) Aid on station. (c) Aid adequately marks hazard/channel. (d) Light List/ATONIS/Chart have been verified.

  8. APR REMARKS SECTION • Aid On or Off Station when found. • Light List verification. • ATONIS verification. • Chart verification. • Reason for ATON visit. • Departures from normal procedures (if any). • Inclined Angle Corrections (if applicable). • If excursion was used, the method used to determine excursion must be listed. • Any other information that may be required by the district office.

  9. Positioning Equipment • DGPS – Primary NMEA Strings – GGA,GSA,GSR,GST HDOP-zero bad, no max Not updating for 3 min bad • GPS - NMEA String – GGA HDOP-zero bad, more than 20 bad • CO / OINC call if Aid is ON/OFF Station • wheretherehasbeenanonboardequipment, (hardware)configurationchange, the verificationprocedure in enclosure(7)mustbe performed priorto using the DGPSequipment forpositioning
