RampTableManager#

class RampTableManager#

Bases: object

Handles ramp-frequency table integration for real DSN measurement models.

Provides static utilities to locate the correct ramp-table interval for a query epoch and to integrate the piecewise-linear transmit frequency over an observation window, supporting multi-segment and day-spanning cases.

Notes

This class is a work-in-progress; the interface may change as additional DSN data types are supported.

Methods

integrate(ramp_table, t1_q_sec, t2_q_sec, ...)

Integrate the piecewise-linear transmit frequency over a query window.
static integrate(ramp_table: dict, t1_q_sec: float, t2_q_sec: float, t1_q_doy: float, t2_q_doy: float)#

Integrate the piecewise-linear transmit frequency over a query window.

Parameters:

  • ramp_table (dict) – Ramp-table data with five entries (indexed 0–4): seconds of day, day-of-year, reference frequency [Hz], frequency rate [Hz/s], and ramp-type flag.

  • t1_q_sec (float) – Start of the integration window in seconds of day.

  • t2_q_sec (float) – End of the integration window in seconds of day.

  • t1_q_doy (float) – Day-of-year corresponding to t1_q_sec.

  • t2_q_doy (float) – Day-of-year corresponding to t2_q_sec.

Returns:

  • f_int (float) – Integrated frequency [Hz·s] over the query window.

  • aux (dict) – Auxiliary debug quantities (segment boundaries, per-segment frequencies, day-span flag, etc.).
