(E)TSO-C196a, or a later version as in force from time to time; or
(c) a GNSS receiver or system which meets the following requirements:
 (i) is certified by an NAA for use in flight under the I.F.R.;
 (ii) has included in its specification and operation the following:
            (A) FDE, computed in accordance with the definition at paragraph 1.7.3 of RTCA/DO-229D;
            (B) the output function HPL, computed in accordance with the definition at paragraph 1.7.2 of RTCA/DO-229D;
            (C) functionality that, for the purpose of HPL computation, accounts for the absence of the SA of the GPS in accordance with paragraph 1.8.1.1 of RTCA/DO-229D; or
(d) another equivalent system authorised in writing by CASA.
Note   The following GNSS receivers meet the requirements of clause 3, namely, those certified to (E)TSO‑C145a or (E)TSO‑C146a, or later versions, or those manufactured to comply with (E)TSO‑C196a.

      GNSS position source equipment — standard for aircraft manufactured before 8 December 2016

      4 For an aircraft manufactured before 8 December 2016, the geographical position transmitted by the ADS-B transmitting equipment must be determined by:
(a) a GNSS receiver or system that complies with the requirements of clause 3, other than sub‑subparagraph 3 (c) (ii) (C) which is optional; or
(b) an equivalent GNSS receiver or system that has been approved in writing by CASA.
Note   The following GNSS receivers meet the requirements of clause 4, namely, those certified to (E)TSO‑C145a or (E)TSO‑C146a, or later versions, or those manufactured to comply with (E)TSO‑C196a. Some later versions of GNSS receivers certified to (E)TSO-C129 may also meet the requirements, i.e. those having FDE and HPL features incorporated.

      Altitude source equipment — standard

      5 The pressure altitude transmitted by the ADS-B transmitting equipment must be determined by:
(a) a barometric encoder of a type that is authorised in accordance with (E)TSO‑C88a, or a later version as in force from time to time; or
(b) another equivalent system authorised in writing by CASA.

(a) it has been approved or accepted by:
 (i) the NAA of a recognised country, as meeting the standards of EASA AMC 20-24 or EASA CS-ACNS; or
 (ii) the FAA, as meeting the standards of 14 CFR 91.225 for 1090 Megahertz (MHz) Extended Squitter ADS-B; and
(b) the aircraft flight manual attests to the approval or acceptance; and
