GPS means Global Positioning System.
HPL means the horizontal protection level of the GNSS position of an aircraft as an output of the GNSS receiver or system.
integrated TABS device means a device with integrated Class A TABS and Class B TABS functionality.
Mode A is a transponder function that transmits a 4-digit octal identification code for an aircraft's identity when interrogated by an SSR.
Mode A code is the 4-digit octal identification code transmitted by a Mode A transponder function.
Mode C is a transponder function that transmits a 4-digit octal identification code for an aircraft's pressure altitude when interrogated by an SSR.
Mode S is a transponder function that uses a unique aircraft address to selectively call individual aircraft and support advanced surveillance using Mode S EHS, Mode S ELS, or Mode S ES capabilities.
