Показана актуальность обеспечения целостности сигналов (ЦС) в системах автономной навигации (САН) космических аппаратов (КА). В целях технологической независимости и импортозамещения предложено использовать для этого отечественную систему компьютерного моделирования электромагнитной совместимости. Представлены результаты анализа ЦС реальных печатных плат САН КА. Для анализа использован квазистатический подход, реализованный в системе TALGAT. Рассмотрены три показательных примера. Сначала выполнена оценка влияния граничных условий на форму сигнала в связанных трассах с учетом и без учета потерь в проводниках и диэлектриках. Затем выполнены оценки уровня перекрестных наводок и коэффициента передачи в пятипроводной трассе во временной и частотной областях. Рассмотрен наихудший случай, когда на один проводник одновременно воздействуют все остальные. Наконец, выполнена оценка синхронизации сигналов в дифференциальной паре.

Shows the relevance of ensuring signal integrity (CA) autonomous navigation systems (SAN) spacecraft (SC). For technological independence and import substitution suggested use for this domestic system of computer simulation of electromagnetic compatibility. Presents the results of the analysis of CA real PCB SAN KA. For the analysis used the quasi-static approach implemented in the TALGAT system. Consider three illustrative examples. First evaluated the influence of boundary conditions on the signal form in related tracks with and without losses in conductors and dielectrics. Then run cross-level assessment tips and gain in pâtiprovodnoj road in time and frequency domains. Considered the worst case, when on one conductor simultaneously affect all the others. Finally, evaluated the differential signal pair synchronization.

The urgency of ensuring the integrity of the signal (CA) systems autonomous navigation (SAN) spacecraft (SC). In order to import technological independence and proposed to use this domestic system of computer modeling of electromagnetic compatibility. The results of the analysis of the actual PCB CA SAN spacecraft. For the analysis used a quasi-static approach, implemented in the TALGAT. We consider three illustrative examples. Initially estimated influence of boundary conditions on the shape of the signal paths associated with and without losses in conductors and dielectrics. Then follow the assessment of the level of crosstalk and gain five-wire to the track in time and frequency domains. Considered the worst case, when one conductor simultaneously affect all the others. Finally, the estimated timing of signals in the differential pair.

For the analysis used-belted approach that is implemented in the system Talgat. Consider three illustrative examples.First, performed an evaluation of impact boundary conditions on the signal in the form of highways, taking into account and without taking into account losses in the conductors and dielectrics.Then implemented assessment of the level and cross-coupling ratio in пятипроводнои highway in time and frequency fields. Considered worst case,When the one conductor simultaneously all the rest. Finally, complete the assessment timing signals in the differential pair.
