spicekit 0.2.1

Python bindings for spicekit: pure-Rust NAIF kernel readers (DAF/SPK/PCK/text kernels).

spicekit (Python)

Python bindings for spicekit, a pure-Rust reader for NASA/NAIF SPICE kernel formats (DAF, SPK, PCK, text kernels). Independent of the CSpice toolkit.

Install

pip install spicekit

Development install (from the workspace root):

maturin develop --release --manifest-path crates/spicekit-py/Cargo.toml

Usage

import spicekit

spk = spicekit.NaifSpk("/path/to/de440.bsp")
state = spk.state(target=399, center=0, et=0.0)  # (x, y, z, vx, vy, vz)

pck = spicekit.NaifPck("/path/to/earth_latest_high_prec.bpc")
m = pck.sxform("J2000", "ITRF93", et=0.0)  # 6x6 state-transform matrix

code = spicekit.naif_bodn2c("EARTH")  # 399
name = spicekit.naif_bodc2n(399)      # "EARTH"
bindings = spicekit.naif_parse_text_kernel_bindings("/path/to/ids.tf")

Surface

• NaifSpk(path): state, state_batch, state_batch_in_frame, segments.
• NaifPck(path): euler_state, sxform, pxform, sxform_batch, pxform_batch, rotate_state_batch, segments.
• NaifSpkWriter(locifn): add_type3, add_type9, write.
• naif_bodn2c(name) / naif_bodc2n(code): built-in NAIF body-code table.
• naif_parse_text_kernel_bindings(path): parse NAIF_BODY_NAME ↔ NAIF_BODY_CODE assignments from text kernels.
