TEC Disturbance Index
This index is defined as the mean deviation of the current conditions for the Total Electron Count (TEC) in the ionosphere from a 15-day running median reference data. An index of 1.5 mean there is a deviation of 150% between the current and the average TEC values. It is representative of the deviation of current ionospheric conditions from those expected by an usual GPS receiver. This deviation can cause a position error if it remain uncorrected. For the real GPS position errors refer to the L1 map below.

Current S4 Index (Ionosphere)
S4 Index
Ionospheric scintillation occurs when a radio frequency signal traverses a region of small scale irregularities in electron density in the ionosphere. This is a rapid fluctuation of radio-frequency signal amplitude. The S4 Index quantified this amplitude scintillation with a measure of the short timescale fluctuation in the signal to noise of a transmission. Values over 0.6 indicate strong scintillation which can cause loss of lock on a GPS signal. A scintillation index below 0.3 is unlikely to have any affect on GPS.

  • Inland Waters Resources: free charts of inland rivers

    Links to free inland vector charts of Austria, Belgium, Croatia, Czech Republic, France, Hungary, Romania, Netherlands, Serbia, Switzerland, USA... By Dacust.

  • Port websites (Shipping Guides Ltd)

    This is a list of port websites by Shipping Guides Ltd. The list is classified by country.

  • Marine Traffic / AIS map

    Ths web site provides free real-time information to the public, about ship movements and ports, mainly across the coast-lines of many countries around the world. The project is currently hosted by the University of the Aegean, Greece. The initial data collection is based on the Automatic Identification System (AIS).

  • Admiralty EasyTide (UKHO)

    The service provides tidal data for over 7000 ports worldwide together with a host of other useful information - make Admiralty EasyTide your first port of call for reliable tidal information. Free predictions for today and the next 6 days.

  • Horaires des marées (SHOM)

    Cette application permet de calculer la marée dans les principaux ports du monde et pour tous les ports, principaux et secondaires, de France métropolitaine. La référence de hauteur utilisée pour les prédictions de marée est le zéro des cartes qui, en général, correspond approximativement au niveau des plus basses mers (LAT : Lowest Astronomical Tide pour les Anglais). Il est possible d'insérez sur son propre site Internet les horaires de marée sous forme d'une vignette petite ou grande.

  • PREVIMer

    Coastal observations and forecasts for the coastlines of France & Overseas. PREVIMer is a system aiming to provide a wide range of users, from private individuals to professionals, with daily observations and short-term forecasts about the coastal environment along the French coastlines bordering the English Channel, the Atlantic Ocean, and the Mediterranean Sea: currents, waves, winds... All information contained on or available through this Web Site is for general information purposes only and does not constitute any investment advice. It can not be discerned or used with absolute reliability by anybody for a personal or professional activity such as maritime navigation. PREVIMer does not replace offical forecast, warning and alert services nor official tide table predictions. Forecasts use French legal time. Maximum waves may be up to twice the significant height.

  • Ice Logistics Portal

    The Ice Logistics Portal was created as a joint initiative of the International Ice Charting Working Group, the JCOMM Expert Team on Sea Ice and Polar View for the International Polar Year. 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.
