ADS-B INFORMATION


Automatic Dependent Surveillance - Broadcast (ADS-B) is a precise satellite-based surveillance system. ADS-B Out uses GPS technology to determine an aircraft's location, airspeed and other data, and broadcasts that information to a network of ground stations, which relays the data to air traffic control displays and to nearby aircraft equipped to receive the data via ADS-B In. Operators of aircraft equipped with ADS-B In can receive weather and traffic position information delivered directly to the cockpit.

ADS-B's original purpose was to provide better traffic information to pilots and to ground-based controllers to allow more efficient use of the national airspace (NAS). This system, called ADS-B "Out," transmits information from the aircraft to ground stations. Upon receipt of this data, the ground station replies by sending a stream of traffic information to the transmitting aircraft and, because it's broadcast not point-to-point, to all other aircraft in the area. Crucially, no traffic information is broadcast from a ground station (978 frequency) unless there is an aircraft nearby (within a 15 NM radius and within 3,500 ft AGL) that is equipped with an ADS-B Out system. ADS-B Out requires a transmitter. However, the FCC and FAA only allow transmitters on certified systems. The FAA does not allow any portable system (like one connected to an iPad) to be certified. Thus, it is impossible to purchase a portable ADS-B Out system; you must purchase a certified system and have it installed in your plane to get ADS-B Out. In other words, although the ground stations have traffic information, they will only broadcast it when an aircraft with a certified ADS-B Out system is within 15 NM of the ground station; there can be several ADS-B In receivers in an area and the ground station will not transmit traffic unless there is also an ADSB Out system in the area. Moreover, the data transmitted from the ground stations is not all the traffic in the area; it is specifically tailored for the aircraft that broadcast its location to the ground station so the ground station only sends targets near that aircraft (+/- 15 NM, +/- 3500 ft) not necessarily near you. Thus, it's entirely possible that an aircraft eavesdropping on traffic meant for another plane may not see a target that is very close to it. The problem this creates cannot be understated. An ADS-B receiver that is not receiving traffic information may not be receiving it either A) Because there is no other plane in the area or B) Because there is simply no ADS-B Out plane in the area. The receiver cannot tell the difference. Thus, a pilot looking at an iPad screen with ADS-B traffic can be misled into believing there is no traffic when, in fact, there is considerable traffic but none with ADS-B Out. Even worse, it's possible to see some traffic on the iPad but not see targets that are dangerously close to you simply because those targets are not close enough to the ADS-B Out equipped plane that triggered the transmission. We believe this is dangerous and, therefore, strongly advise that pilots rely primarily on their eyes, not their iPad, when looking for traffic.

 

ADS-B OUT DATALINK RADIOS

There are two types of datalink radios - a 1090 MHz (1090ES) system or 978 MHz Universal Access Transceiver (UAT). A 1090ES datalink radio includes a new or modified Mode S transponder paired with a certified WAAS GPS ADS-B position source. A 1090ES is required for aircraft operating at FL180 and above. A 978 UAT also pairs with an approved WAAS GPS ADS-B position source and other aircraft systems and communicates with the network and other aircraft.

1090ES or 978 UAT?

Aircraft that fly below FL180 can fulfill ADS-B Out requirements with either a 1090ES or 978 UAT datalink radio. However, a 978 UAT is highly recommended because:

+ It uses efficient, reliable, low-power, high-integrity digital data transmissions vs. 70-year-old radar-based technology

+ It only requires a simple retrofit installation for most aircraft.

+ The 978 UAT paired with an approved ADS-B position source works with existing Mode A and C transponders. The 1090ES option requires replacement or modification of an existing transponder.

+ The 978 MHz frequency has ample capacity for increased airspace use and for aviation data services while the 1090 MHz frequency is already congested and lacks capacity for growth.

ADS-B In Services

Equipping for ADS-B Out gives pilots the option to use a certified ADS-B In receiver to take advantage of valuable weather and traffic data without added subscription fees or dedicated equipment. An ADS-B In receiver is optional and can be installed at the same time as ADS-B Out or added later.

ADS-B In Traffic

ADS-B In systems receive traffic data from TIS, TIS-B, TAS, TCAD and TCAS systems that operate on the 1090 MHz frequency. In addition all ADS-B Out equipped aircraft can "see" each other when within line of sight. Traffic data is broadcast on both the 1090 and 978 MHz frequencies.

ADS-B In FIS-B Weather and Other Services

ADS-B In systems also receive weather and other data services called Flight Information Services- Broadcast (FIS-B). FIS-B is broadcast only on the 978 MHz frequency . ADS-B In receivers also will support future broadcast services made possible by abundant capacity on the 978 MHz frequency.

ADS-B Benefits are here and now

Aircraft owners may be tempted to wait until the Jan. 1, 2020 ADS-B Out draws near. But it's more sensible to equip aircraft now and get the benefits of ADS-B immediately.

The positional accuracy and national coverage of ADS-B Out can increase the availability of VFR Flight Following services and enable more efficient IFR routing. ADS-B Out significantly improves the ability to locate a missing aircraft and provide emergency assistance when needed. Equipping for ADS-B In adds the cost-saving and safety benefits of in-cockpit weather services.

By equipping now aircraft owners can reduce installation downtime. Avionics shops across the country face a potential capacity crunch as about 140,000 GA aircraft require ADS-B installations. That means well over 100 installations per day before the deadline in addition to the regular workload of other installations, repairs, avionics updates and maintenance.

Single-Band verses Dual Band ADS-B in Equipment

Single Band ADS-B in equipment only picks up on the 978 UAT frequency.  Which is the frequency that gives you weather and traffic information from the ground station only.  With Single band you cannot see any 1090 transmissions.  Dual band picks up both 978 and 1090 transmissions which allow you to see a better traffic picture than single band.  Typically dual band receivers cost more than the single band. 

All ADS-B receivers work on the 978 MHz frequency to receive ground-based weather and traffic. Some of the more expensive units also receive (but not transmit) on the 1090 MHz frequency. These units can receive traffic from an effectively larger area because they can receive "relayed" information from other aircraft. Weather is never sent over the 1090 band. In other words, if Plane A is equipped with a 1090 MHz receiver but is too far from a ground station to receive data, it might receive traffic but not weather data from Plane B if Plane B is between Plane A and the ground station and Plane B has a 1090 transmitter (ADS-B Out).
