Radio navigation aids provide pilots with vital information about their aircraft&#;s position, course and altitude. They offer precise and accurate guidance to pilots, enabling more efficient airspace management and helping to optimize air traffic routes and procedures. ICAO recently published the 8th Edition of Annex 10 &#; Aeronautical Telecommunications &#; Volume I &#; Radio Navigational Aids. This technical document defines, for international aircraft operations, the systems that need to be in place to provide radio navigation aids used by aircraft in all phases of flight.

The Standards and Recommended Practices (SARPs) and guidance material in this Volume outline the necessary specifications for radio navigation aids that include: the global navigation satellite system (GNSS), instrument landing system (ILS), microwave landing system (MLS), very high frequency (VHF) omnidirectional radio range (VOR), non-directional radio beacon (NDB) and distance measuring equipment (DME). This Volume covers essential aspects of power requirements, frequency, modulation, signal characteristics and monitoring needed to ensure that suitably equipped aircraft can receive navigation signals in all parts of the world with the requisite degree of reliability.
Crucial for safe air navigation
Annex 10, Volume I addresses the technical requirements and specifications for radio navigational aids used in aviation. The main objectives are to:
- ensure the standardization of radio navigational aid systems worldwide to promote uniformity and enhance safety in international air navigation.
- provide guidance to Member States on the installation, operation, and maintenance of radio navigational aids to achieve consistent performance and reliability.
Supporting evolution in infrastructure
In keeping with the nature of aviation technology, this new edition of Annex 10, Volume I looks to the future. It supports the introduction of a dual-frequency, multi-constellation (DFMC) global navigation satellite system (GNSS) reflecting the ongoing evolution of the global GNSS infrastructure and facilitate its fruition by international civil aviation.
As part of the evolution, multiple GNSS constellations offering dual-frequency signals are being introduced into service by the United States (GPS modernization), the Russian Federation (GLONASS modernization), the European Union (Galileo constellation) and China (BeiDou Navigation Satellite System (BDS) constellation). DFMC GNSS offers an opportunity to further enhance GNSS robustness, navigation performance and operational benefits.
Technical specifications and maintenance
Annex 10 Volume I details the technical specifications, installation requirements, maintenance procedures, and safety considerations for each type of radio navigational aid. These specifications help ensure that the systems are reliable, accurate, and compatible with each other, which is vital for seamless air navigation, especially in busy airspace with numerous aircraft. With radio navigation aid technologies continuously evolving, it is essential that Member States and aviation stakeholders follow the Standards and recommended practices in Annex 10 Volume I in order to implement these technologies.
It is worth noting that implementation of DFMC GNSS is not mandatory and will be driven by the specific cost/benefit and policy considerations that apply to individual States in consultation with aircraft and airport operators and international organizations.
Annex 10 Volume I reach
The primary users of Annex 10, Volume I are local civil aviation authorities (CAAs) and air navigation service providers (ANSPs) who bear international obligations and responsibilities in regulating and facilitating safe and efficient flight operations. These regulatory bodies and service providers necessitate detailed information on radio navigation specifications, implementation guidelines, and training requirements. CAAs oversee the implementation of radio navigational aid systems with the support of manuals like Doc , Doc and Doc . ANSPs follow the guidance on the installation, operation, and maintenance of radio navigational aids to achieve consistent performance.
These specifications help ensure that the systems are reliable, accurate, and compatible with each other, which is vital for seamless air navigation, particularly in a busy airspace with numerous aircraft. From an industry standpoint, the primary target audiences for the provided information encompass aircraft operators, air traffic management personnel, and aviation training centers. These professionals rely on comprehensive information and guidelines to fulfil the installation requirements and maintenance procedures for operations and training on radio navigational aids.

Marker to assist in safe passage making
"ATON" redirects here. For other uses, see Aton.
A navigational aid (NAVAID), also known as aid to navigation (ATON), is any sort of signal, markers or guidance equipment which aids the traveler in navigation, usually nautical or aviation travel. Common types of such aids include lighthouses, buoys, fog signals, and day beacons.
According to the glossary of terms in the United States Coast Guard Light list, an aid to navigation (ATON) is any device external to a vessel or aircraft specifically intended to assist navigators in determining their position or safe course, or to warn them of dangers or obstructions to navigation.
Main article: Lateral mark
Lateral marks indicate the edge of the channel. The standards are defined by the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA). Approaching harbour port a vessel leaves port hand marks to port (left) and starboard hand marks to starboard (right). Port hand marks are cylindrical, starboard marks are conical. If the mark is a pillar or spar shape, then a topmark is fitted which is either cylindrical or conical as appropriate.[1]

IALA divides the world into two regions: A and B. Region B is the Americas (excluding Greenland) along with Japan, Korea and the Philippines. Region A is the rest of the world. In region A port marks are red and starboard marks green. In region B port marks are green and starboard red.[1] Where marks are numbered red marks have even numbers and green marks have odd numbers.
Where a channel divides the mark at the junction is called a "preferred channel mark" or "junction buoy". The mark has the colour and shapes corresponding to the preferred channel with a band of the other colour to indicate it is the other hand mark for the subsidiary channel.[1] In IALA region A where a minor channel branches off to port the mark at the junction would be a red cylinder with a green band. The red cylinder is a port hand mark for the main channel, the green band indicates a starboard mark for the minor channel. In IALA region B the colours (but not shapes) are reversed.
Main article: Cardinal mark
Cardinal marks warn of a danger (wrecks, shoals, bends, spits etc.) and indicate the safe water past the danger. There are four varieties: north, east, south and west. A north cardinal mark is placed to the north of a hazard and indicates safe water is to the north of the mark. East, south and west are placed accordingly. Cardinal marks are yellow and black with two cones at top marks. There is no difference between IALA region A and B.
Black with a horizontal red band and two black balls as a top mark. The mark indicates a danger (shoal, rock, wreck etc.) which is isolated with safe water all around.
Main article: Safe water mark
Red and white vertical stripes with a single red sphere for a top mark. It indicates that there is safe water all around it. The usual use is to indicate the start of a channel or port approach.
Main article: Emergency wreck buoy
Indicates a newly discovered or created danger that is not yet marked on charts (or in update notices thereto). The mark is used for a short time until the danger is either removed or else marked conventionally with lateral or cardinal marks. The mark has blue and yellow vertical stripes and a yellow and blue light. The topmark is a vertical yellow cross.
Yellow with an "X" topmark. Used to mark other features such as swimming areas, anchorages, pipelines. The exact reason is marked on charts.
A sector light is one which shows different colours depending upon the angle of approach. They are commonly used to indicate the safe channel (white) and show red or green if the vessel is out of the safe channel. IALA requires the light colours to follow the appropriate region (A or B) colour scheme.
There are also other markers that give information other than the edges of safe waters. Most are white with orange markings and black lettering. They are used to give direction and information, warn of hazards and destructions, mark controlled areas, and mark off-limits areas. These ATONs do not mark traffic channels.
On non-lateral markers, there are some shapes that show certain things:
- Squares[10]
- show information, including places to find food, supplies, and repairs. They sometimes show directions.
- Diamonds[10]
- warn about dangers like rocks, construction, dams, or stumps.
- Circles[10]
- mark a controlled area such as no wake, idles speed, speed limit, or ski zone.
- Crossed diamonds[10]
- show areas off limits to all boats, like swimming areas and dams.
AtoNs can be integrated with automatic identification system (AIS). AIS transmitted form an actual aid (buoy, lighthouse etc.) is termed a "real AIS AtoN".[11]
If it is impractical to equip the AtoN with an AIS transponder an AIS shore station can be assigned to transmit AIS messages on behalf of the AtoN. This is known as a "synthetic ATON". Synthetic AtoNs can be either "monitored synthetic AtoNs" or "predicted synthetic AtoNs". The former have a link between the AtoN so that the AIS station can confirm the AtoNs status. The latter have no link and the AIS system just predicts that the AtoN is where it should be.
If there is no real AtoN (such as for the short term marking of a wreck) then a "virtual AIS AtoN" is used.
Each AIS AtoN must have a unique Maritime Mobile Service Identity (MMSI) number. Synthetic and virtual AIS AtoNs mark their messages as repeats to indicate that the location of the transmitter is not the location of the AtoN.
Lead marks (as in "leading a ship into a safe place") and lights are fixed markers that are laterally displaced to allow a mariner to navigate a fixed channel along the preferred route. They are also known as "channel markers".[14][failed verification] They can normally be used coming into and out of the channel. When lit, they are also usable at night. Customarily, the upper mark is up-hill from the lower (forward) mark. The mariner will know the geometry of the marks/lights from the navigational chart and can understand that when "open" (not one above the other) the ship needs to be navigated to "close" the marks (so one is above the other) and be in the preferred line of the channel.
In some cases, the lead marks/lights are provided by lasers, as in the laser channel under the Tasman Bridge on the Derwent River at Hobart, Tasmania.
