About this course
This course will provide you with the practical understanding and knowledge of celestial navigation, including the ability to fix the vessel's position and determine compass error using celestial observations.Â
What you'll study
Using celestial bodies to fix positionÂ
- Identify and select the most suitable celestial bodies in the twilight periodÂ
- Determine the time of visible rising and setting of the sunÂ
- Use acceptable methods to calculate altitude and azimuthÂ
- Accurately plot lines of position obtained from a sight-to-fix positionÂ
- Use the nautical almanac and calculator or nautical tables to find a position line from an altitude obtained by a sextant and time obtained from a chronometer.Â
Determining latitude by celestial meansÂ
- Calculate the latitude by PolarisÂ
- Calculate the latitude by meridian altitude of the sun or planetÂ
- Calculate the time of meridian altitude of the sun or planet.Â
Determining compass error by celestial meansÂ
- Determine compass error by amplitude of the sun or a planetÂ
- Determine compass error by azimuth or the sunÂ
- Determine compass error by azimuth of a star or planet.Â
Useful tips
- Read through the exam syllabus.Â
- Your pass certificate is valid for one year.Â
- You do not need a Notice of Eligibility (NoE) to attend this course. However, you will need an NoE for your MCA oral exam. Download the application form. Allow at least six weeks (currently even more) for the NoE to be processed by the MCA.Â
- Do the ‘proper’ PSCRB course instead of ‘Advanced Sea Survival for Yachtsmen’. The latter has not got an STCW Code which has the following implications: Not all flag states recognise the Advanced Sea Survival, meaning you might have to do the PSCRB later anyway. Your certificate will have a negative endorsement (‘not to be used on vessels with davit-launched life rafts’). There is also no updating course available for the Advanced Sea Survival.Â
- Pre-study makes the difference. That’s why we send you the course notes as soon as you book. Â
Notice of Eligibility (NoE) and oral exams guidance
When you have accrued sufficient sea time to sit an oral exam with the MCA, you are required to apply for a Notice of Eligibility (NoE).Â
This form can be downloaded from the MCA website and must be returned with original copies of your supporting documentation (sea service testimonials, STCW certificates, exam pass certificates and ENG1) to prove you are eligible for an oral exam.Â
Once you have your NOE you can book your oral exam at any of the MCA offices throughout the UK. The MCA office you have chosen will not confirm your booking until you have received your NOE. Be aware they do have busy periods, so it is best to book your oral exam well in advance to ensure you get your preferred date.Â
A Notice of Eligibility is valid for five years from date of issue, and for three years after a successful oral exam. You must apply for your NOE well in advance of your anticipated exam date as they can take up to six weeks to be processed.Â
