  1. ATON BM1 BAGLEY BM1 KANE (THE MAN)

  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

  10. EXCURSION METHODS • L METHOD CHAIN LENGTH – WATER DEPTH 3 • HYPOTENUSE METHOD CHAIN LENGTH X 2 – WATER DEPTH X 2 SQUARED

  11. ATON ADMIN • What is covered? • Marking of wrecks and obstructions? • CO/OINC responsibilities? • ATON SERVICING FLOWCHART (SIF)

  12. What is Covered? • Training • Correction of Discrepancies • Duties & Operations of ATON Units • Lighthouses • External Relations • Navigation Info • Non – USCG maintained Aids • Establishment, Review, and Modification of ATON • Management & Admin of Short Range ATON

  13. Marking of Wrecks and Obstructions…… • Inform owner of responsibility to mark (Federal Law) • Owner pays expense to mark (keep at a min) • Must be reported to District Commander immediately followed by a Hazard to Navigation Message • The name, description, and accurate location of the wreck. • The name and address of the owner or his agent. • Depth of water over the wreck. • The action or intent of the owner to mark the wreck, and when such action will be taken. • The type, description, and location of the marking, if any. • An opinion as to whether or not immediate marking of the wreck by the Coast Guard is necessary for the protection of navigation.

  14. Marking of Wrecks and Obstructions (cont) • CG may or may not mark • Use appropriate marking • If longer than 30 days, must make permanent

  15. CO/OINC RESPONABILTIES • Contacting owner of wreck or obstruction • Discrepancy Response Factor (DRF) must sign • ATONIS • Ensure a Federal Aid Information Document is updated • Ensure Battery Tracking is used from cradle to grave
