v1.0.8

What's Changed

• RC 1.0.8 by @semuadmin in #38

1. As of October 2025, u-blox have discontinued all their encrypted SPARTN services (PointPerfect L-Band and MQTT). For this reason, the cryptography package used for SPARTN message decryption is now an optional dependency for pyspartn. To enable decryption support, install cryptography separately e.g.

python3 -m pip install --upgrade cryptography

2. Minimum actively supported Python version updated to 3.10 (3.9 EOL end October 2025).

v1.0.7

What's Changed

• RC 1.0.7 by @semuadmin in #37

1. Make SPARTN decryption (and associated cryptography library dependencies) an optional feature, to avoid a hard dependency on the cryptography library (which can be problematic on some platforms). To install without SPARTN decryption support, use python3 -m pip install pyspartn --no-deps.

v1.0.6

What's Changed

• RC 1.0.6 by @semuadmin in #36

1. Update build configuration and minimum cryptography version - no functional changes.

v1.0.5

What's Changed

• RC 1.0.5 by @semuadmin in #34

1. Add new optional timetags argument to SPARTNReader & SPARTNMessage, to allow them to use any available 32-bit gnssTimeTag values from the incoming datastream in order to decrypt messages (rather than having to provide an explicit basedate).
   • The timetags argument is a dict of the format {0: 495763673, 1: 485866844, 3: 410283479} where the key represents the message subType (0 = GPS, 1 = GLO, 2 = GAL, etc.), and the value represents the 32-bit gnssTimeTag value from the data stream (if present).
   • If a nominal decryption basedate of TIMEBASE (datetime(2010, 1, 1, 0, 0, tzinfo=timezone.utc)), or integer 0, is passed to SPARTNReader, it will endeavour to capture 32-bit gnssTimeTag values for each msgSubtype from the incoming data stream and pass these to SPARTNMessage via the timetags arg to decrypt messages of the same msgSubtype with 16-bit gnssTimeTags (timeTagtype=0).
   • NB: this will only work if the data stream contains valid 32-bit gnssTimeTag values for the same msgSubtype e.g. if an HPAC message with msgSubtype=2 precedes a GAD or OCB message with msgSubType=2 and timeTagtype=0 - until such an eventuality occurs, decryption of GAD or OCB messages may fail!
   • Always use quitonerror=ERRLOG or quitonerror=ERRIGNORE when setting basedate to TIMEBASE.
2. SPARTMMessage will now return explicit SPARTNDecryptionError if unable to successfully decrypt/decode message using key and basedate provided.

v1.0.4

What's Changed

• RC 1.0.4 by @semuadmin in #33

1. Add active support for Python 3.13
2. Drop active support for Python 3.8 - now EOL as at October 2024.
3. Rename socket_stream to socket_wrapper for clarity.

v1.0.3

What's Changed

• add troposphere coefficient offsets by @semuadmin in #31

1. Fixed offsets added to troposphere attributes, in accordance with SPARTN 2.0.2 specification:

   • SF043 (Area average vertical hydrostatic delay )-> add 2.3m
   • SF045 (Small troposphere coefficient T00) -> add 0.252m
   • SF048 (Large troposphere coefficient T00) -> add 0.252m

   Thanks for @jonathanmuller for contribution.

Fixes #30

Full Changelog: v1.0.2...v1.0.3

v1.0.2

What's Changed

• Enhance exception handling to Include SPARTNStreamError. by @semuadmin in #28

1. Enhance exception handling to Include SPARTNStreamError. Fixes issue where SPARTNStreamError may still be raised even if ERRIGNORE is set.

Full Changelog: v1.0.1...v1.0.2

v1.0.1

What's Changed

• Rc 1.0.1 by @semuadmin in #27

1. Internal enhancements to logging and exception handling.

Full Changelog: v1.0.0...v1.0.1

v1.0.0

What's Changed

• Rc 1.0.0 by @semuadmin in #26

1. Add payload attributes for PRN, Phase Bias and Code Bias values, derived from the corresponding bitmasks for each constellation type. e.g. PRN_01=3, PhaseBias_01_03=L2L, CodeBias_02_03=C2L.
2. Add examples parse_ocb.py & parse_hpac.py illustrating how to convert parsed and decoded OCB and HPAC messages into iterable data structures.
3. Add naive2aware(dt,tz) helper method - convert naive basedates to aware with UTC timezone.
4. Internal enhancements to simplify basedate handling.
