What is a TSO-C129 GPS?

TSO – Technical Standard Order TSO-C129 and TSO-C196 refer to non-WAAS GPS systems. TSO-C146 refers to WAAS-enabled GPS systems. When using non-WAAS GPS for navigation and instrument approaches, any required alternate airports must have an approved and operational instrument approach procedure other than GPS.

What is SA aware GPS?

SA-Aware GPS receivers are designed to recognize that SA is inactive and optimize the performance from GPS. GPS receivers that comply with the performance requirements of TSO-C196, Airborne Supplemental Navigation Sensors for Global Positioning System Equipment Using Aircraft-Based Augmentation, are SA-Aware receivers.

Do WAAS GPS use RAIM?

WAAS enhances the reliability of the GPS system and thus no longer requires a RAIM check if WAAS coverage is confirmed to be available along the entire route of flight; in this case the pilot can plan the flight to a destination and file an alternate airport using only the WAAS navigation capabilities.

Do you need RAIM for GPS approaches?

IFR GPS units must automatically perform a RAIM check before beginning an approach. However, performing a RAIM check prior to leaving the ground will better enable pilots to plan ahead and is recommended specifically for pilots without baro-aiding (see below).

What is TSO 146?

TSO-C129 is an older technical standard for GPS for inflight navigation.

How many GPS satellites are required for WAAS?

6 satellites
The WAAS receiver adds a fault detection & exclusion (FDE) feature requiring a minimum of 6 satellites to detect and exclude a faulted satellite.

How accurate is ADS-B?

Positional Accuracy: The requirement for ADS-B Positional Accuracy for Terminal Airspace is 303.8 feet (0.05 nautical mile). The requirement for ADS-R Positional Accuracy for Terminal Airspace is 607.6 feet (0.1 nautical mile). In all cases, the Horizontal Positional Accuracy was within limits.

What is navigation integrity category?

Navigation Integrity Category (NIC) specifies an integrity containment radius around an aircraft’s reported position, as defined in TSO-C166b and TSO-C154c. Total latency is the total time between when the position is measured and when the position is transmitted by the aircraft.

How accurate is WAAS GPS?

Using WAAS, GPS signal accuracy is improved from 20 meters to approximately 1.5 – 2 meters in both the horizontal and vertical dimensions.

What are the different types of GPS approaches?

Steering cues for the most common RNAV GPS approach types range from lateral, left-right guidance for LNAV and LP approaches (left primary flight display view) to those adding vertical guidance—the LNAV/VNAV and LPV approaches, as shown in the right primary flight display view.

What does WAAS stand for?

– Wide Area Augmentation System
Satellite Navigation – Wide Area Augmentation System (WAAS)

How accurate is a WAAS GPS?

Can a TSO-C129 be used as a GPS?

(2) (a) (2): Aircraft using un-augmented GPS (TSO-C129 () or TSO-C196 ()) for navigation under IFR must be equipped with an alternate approved and operational means of navigation suitable for navigating the proposed route of flight. (Examples of alternate navigation equipment include VOR or DME/DME/IRU capability).

When was tso-c196 published by the FAA?

On September 21, 2009, the FAA published TSO-C196, Airborne Supplemental Navigation Sensors for Global Positioning System Equipment Using Aircraft-Based Augmentation; an updated minimum performance standard for GPS sensors not augmented by satellite-based or ground-based systems ( i.e., TSO-C129a Class B and Class C).

Which is more stringent TSO c196 or c145c?

TSO-C145c, TSO-C146c, and TSO-C196 incorporate more stringent standards and testing requirements that make the GPS equipment more accurate and robust than sensors built to the minimum requirements in TSO-C129a.

What does TSO stand for in aviation category?

FAA Home ▸ Aircraft ▸ Aircraft Certification ▸ Design Approvals Technical Standard Orders (TSO) A TSO is a minimum performance standard for specified materials, parts, and appliances used on civil aircraft. When authorized to manufacture a material, part, or appliances to a TSO standard, this is referred to as TSO authorization.
