RADAR CRM verzamelt deze informatie en geeft de data ‘een gezicht’. Door iedere dag de gegevens over de relatie te verzamelen in de applicatie betekent dat:1. Je de klant goed kent2.
Je weet wat er verwacht wordt3. Alle medewerkers dezelfde informatie hebben4. Er gestructureerd gewerkt wordt5. Alle data nog een keer kan worden ingezet om Power BI te vullen.Een goed gevulde CRM applicatie was nog nooit zo belangrijk. De data wordt voor verschillende doeleinden gebruikt en zorgt aan de voorkant dat de klant optimaal wordt geholpen en aan de achterkant dat het bedrijf goed aangestuurd kan worden.
1 Introduction1.1 The Automatic Radar Plotting Aids (ARPA) should, in order to improve the standard of collision avoidance at sea.1 Reduce the work-load of observers by enabling them to automatically obtain information so that they can perform as well with multiple targets as they can by manually plotting a single target; and.2 Provide continuous, accurate and rapid situation evaluation.1.2 In addition to the General Requirements for Electronic Navigational Aids (IMO Res. A.281(VII)), the ARPA should comply with the following minimum performance standards. 3 Performance Standards3.1 Detection3.1.1 Where a separate facility is provided for detection of targets, other than by the radar observer, it should have a performance not inferior to that which could be obtained by the use of the radar display.3.2 Acquisition3.2.1 Target acquisition may be manual or automatic. However, there should always be a facility to provide for manual acquisition and cancellation. ARPA with automatic acquisition should have a facility to suppress acquisition in certain areas.6 Calculated true speed of target.3.7 Trial Manoeuvre3.7.1 The ARPA should be capable of simulating the effect on all tracked targets of an own ship manoeuvre without interrupting the updating of target information.
The simulation should be initiated by the depression either of a spring-loaded switch, or of a function key, with a positive identification on the display.3.8 Accuracy3.8.1 The ARPA should provide accuracies not less than those given in paragraphs 3.8.2 and 3.8.3 for the four scenarios defined in Annex 2. With the sensor errors specified in Annex 3, the values given relate to the best possible manual plotting performance under environmental conditions of plus and minus ten degrees of roll.3.8.2 An ARPA should present within one minute of steady tracking the relative motion trend of a target with the following accuracy values (95 percent probability values).
Scenario/dataRelative course (degrees)Relative speed (knots)C.P.A. Annex 1 to Appendix A to - Definitions of Terms To Be Used Only in Connection With ARPA Performance StandardsRelative course - The direction of motion of a target related to own ship as deduced from a number of measurements of its range and bearing on the radar. Expressed as an angular distance from North.Relative speed - The speed of a target related to own ship, as deduced from a number of measurements of its range and bearing on the radar.True course - The apparent heading of a target obtained by the vectorial combination of the target's relative motion and ship's own motion1.Expressed as an angular distance from North. 1 For the purpose of these definitions there is no need to distinguish between sea or ground stabilization.True speed - The speed of a target obtained by the vectorial combination of its relative motion and own ship's motion1.Bearing - The direction of one terrestrial point from another. Expressed as an angular distance from North.Relative motion display - The position of own ship on such a display remains fixed.True motion display - The position of own ship on such display moves in accordance with its own motion.Azimuth stabilization - Own ship's compass information is fed to the display so that echoes of targets on the display will not be caused to smear by changes of own ship's heading. /Course-up - An intended course can be set to the line connecting the center with the top of the display.Heading - The direction in which the bow of a is pointing. 2 In calculations leading to the accuracy figures quoted in paragraph 3.8, these sensor error sources and magnitudes were used.
They were arrived at during discussions with national government agencies and equipment manufacturers and are appropriate to equipments complying with the Organization's draft performance standards for radar equipment (preliminary) (NAV XXII/WP.14), gyro compasses (NAV XXI/9, Annex X) and logs (preliminary) (NAV XXII/WP.15).Independent studies carried out by national government agencies and equipment manufacturers have resulted in similar accuracies, where comparisons were made.Note: o means “standard deviation”. RadarTarget Glint (Scintillation) (for 200 m length target)Along length of target o = 30 m. (normal distribution)Across beam of target o = 1 m. (normal distribution)Roll-Pitch Bearing. The bearing error will peak in each of the four quadrants around own ship for targets on relative bearings of 045°, 135°, 225° and 315° and will be zero at relative bearings of 0°, 90°, 180° and 270°. This error has a sinusoidal variation at twice the roll frequency.

For a 10° roll the mean error is 0.22° with a 0.22° peak sine wave superimposed.Beam shape - assumed normal distribution giving bearing error with o = 0.05.Pulse shape - assumed normal distribution giving range error with o = 20 meters.Antenna backlash - assumed rectangular distribution giving bearing error ±0.5 maximum. Appendix B to - U.S. Maritime Administration Collision Avoidance System SpecificationA collision system designed as a supplement to both surface search navigational radars via interswitching shall be installed. The system shall provide unattended monitoring of all radar echoes and automatic audio and visual alarm signals that will alert the watch officer of a possible threat. The display shall be contained within a console capable of being installed adjacent to the radar displays in the wheelhouse and may form a part of the bridge console.Provision for signal input from the ship's radars, gyro compass, and speed log, without modification to these equipments shall be made. The collision avoidance system, whether operating normally or having failed, must not introduce any spurious signals or otherwise degrade the performance of the radars, the gyro compass or the speed log.Computer generated display data for each acquired target shall be in the form of a line or vector indicating true or relative target course, speed and both present and extrapolated future positions.
Data shall be automatically displayed on a cathode ray tube or other suitable display contrivance sufficiently bright and unobstructed to permit viewing by more than one at a time.In addition to displaying the collision potential of the most threatening fixed and moving targets, the system shall be capable of simultaneously showing land masses.The system display shall include a heading indication and bearing ring. The system shall also have the capability of allowing the operator to select “head-up” and to cancel the vector or line presentation of any of the targets.

The presentation shall be non-smearing when changing modes or display scales in order to permit rapid evaluation of the displayed data.Target acquisition, for display data purposes, may be manual, automatic or both, as specified by Owner.For any manual acquisition system the alarms shall be initiated by a preset minimum range; and likewise for any automatic acquisition system the alarms shall be initiated by a preset minimum acceptable passing distance (CPA - Closest Point of Approach) and a preset advance warning time (TCPA - Time to Closest Point of Approach). Means shall be provided to silence the audio alarm for a given threat but the alarm shall resound upon a subsequent threat. The visual alarm shall continue to operate until all threats have been eliminated.
