About Nautical Free

Nautical Free provides a list of free nautical charts and online publications.

There is a list by country from letter A to letter V, for each country the organizations and for each organization a list of free online documents (charts, nautical books, notice to mariners...). There is two special lists: one for the international organizations and one for the private companies. There is also a reverse list by type of documents: sailing directions, radio signals, tide tables, nautical charts... You can also find on Nautical Free wave forecast maps for tomorrow, space weather forecast for GPS, how to check your computer clock, as well as information about celestial navigation or about ice navigation...

Au sujet de Nautical Free

Nautical Free fournit une liste de cartes marines gratuites et d'ouvrages nautiques en ligne.

              • pilotage, vts, reporting, radio communications and transmissions

              • An increasing number of ports are introducing specific quarantine reporting requirements with regards to this virus. Its continued spread is also impacting a number of other services. Due to the ongoing and dynamic nature of the situation, mariners should contact the appropriate Port Authority, VTS, Pilot, coastguard, radio station or other designated body covering their planned route and destination, for the latest advice and procedures. Due to the rapidly changing situation, it is advised to check local situation at the earliest opportunity when passage planning.

          • The ionosphere can be the largest source of error in GPS positioning and navigation. Furthermore, under certain conditions, amplitude fading and phase scintillation effects can cause loss of carrier lock and intermittent GPS receiver operation.

            • TEC: Affected by solar activity, Total Electron Content (TEC) describes the total number of free electrons present within one square meter between two points (i.e. between the receiver and satellite). The GPS radio signal is slowed by the presence of free electrons, causing an additional time delay. The larger the TEC quantity, the longer the delay in a received GNSS signal. The delay will cause a range error for the measures of the distance between a satelite and the receiver: one TEC unit causes a range error of 0.162 meter. The range errors will cause a position error if they remain uncorrected. However, this position error will usually be smaller than the range errors. Standard GPS receivers correct by software more than 50% of the range error (More information).

            • Scintillation: Ionospheric scintillation is a rapid fluctuation of radio-frequency signal amplitude. It is generated when a signal passes through the ionosphere in a region with small scale irregularities in electron density. Ionosphere scintillation follows the 'solar cycle' which is affected by maximum sunspot activity and is primarily an equatorial and high-latitude ionospheric phenomenon. Scintillation affects satellites transmission with short-sterm signal fading that can severely stress the tracking capabilities of a GPS receiver. The higher the level of scintillation, the greater the errors (More information).

    • OpenSeaMap - The free nautical chart

      • OpenSeaMap is an open source, worldwide project to create a free nautical chart. There is a great need for freely accessible maps for navigation purposes, so in 2009, OpenSeaMap came into life. The goal of OpenSeaMap is to record interesting and useful nautical information for the sailor which is then incorporated into a free map of the world. This includes beacons, buoys and other navigation aids as well as port information, repair shops and chandlerys. OpenSeaMap is a subproject of OpenStreetMap and uses its database.

    • Resilient Navigation and Timing Foundation

      • Much of the world depends upon satellite systems for precise navigation and timing services. These are exceptionally accurate and dependable, yet GPS/GNSS jamming, spoofing, and other forms of interference appear to be growing in frequency and severity. Neither are space systems immune to severe space weather or cyber-attack. This has the potential for devastating effects on our lives and economic activity. Our goals of deterring jamming and spoofing while encouraging additional resilient services will protect critical infrastructure and make the world a safer place. Include a libray with some of the more important documents in the field.

It is now maintained by the German Bundesamt für Seeschifffahrt und Hydrographie. It is intended to create a convenient point of access to operational sea ice information produced by the world's ice services. Access to products is provided via a series of pre-defined regions for both the Arctic and the Antarctic. Since the primary focus of the Ice Logistics Portal is on operational sea ice data (i.e. ice charts), only the most recent information is displayed for any given region.
