We present the modification of two ESA [European Space Agency] ground stations carried out in order to support the in-flight RF [Radio Frequency] validation of the Proximity Communication Equipment(PCE), part of the International Space Station(ISS). This subsystem plays a critical role during the docking of the Automated Transfer Vehicle(ATV), and has to be tested prior to each ATV launch, to ensure that the RF performance is as expected. For the check-out, an unmodulated signal is transmitted by the PCE during an ISS pass, and received by the two ground stations. Based on the strength of the received signal, the radiation characteristic of the complete PCE can be assessed, and compared with the nominal performance. The measurement process requires calibrating the receiving subsystem, including antenna, front-end and back-end equipment. The adopted calibration procedure, only relying on radio stars measurement, does not require the use of a calibrated source external to the ground station. 3, record 2, English, - proximity%20communication%20equipment

Le système de communications PCE (Proximity Communication Equipment) a été développé et intégré à Toulouse par EADS [European Aeronautic Defence Space] Astrium, dans le cadre du programme ATV [véhicule de transfert automatique] de l'Agence Spatiale Européenne, sous responsabilité d'EADS SPACE Transportation qui est le maître d'œuvre du développement et de la construction du segment spatial de l'ATV. Le PCE est destiné à assurer les communications de proximité pour les 30 derniers kilomètres de vol du futur véhicule cargo européen ATV à son approche de la Station spatiale internationale (ISS). [...] Le PCE est un sous-ensemble intégré. Il est constitué de deux chaînes de communications en bande S, entièrement redondantes. Il comprend deux transpondeurs à spectre étalé, deux équipements de gestion de protocoles CCSDS [Consultative Committee for Space Data Systems] et des équipements radio fréquence. Le PCE sera installé dans le module Zvezda de l'ISS et sera opérationnel durant la phase dite «de proximité» correspondant aux 30 derniers kilomètres du vol ATV et à l'exercice délicat de son arrimage à la Station. Ce rendez-vous orbital automatique représentera une première européenne. Parmi l'ensemble des données de commande et de contrôle qu'il transmettra dans le cadre de sa mission de communications, le PCE fournira à l'ATV les informations de position GPS [système mondial de localization] nécessaires à la navigation relative vers la Station spatiale internationale (ISS). À une distance de 500 m et jusqu'à l'arrimage, la navigation se poursuivra à l'aide d'instruments laser, d'abord avec un télégoniomètre puis avec un vidéomètre pour les phases finales. 3, record 2, French, - syst%C3%A8me%20de%20communication%20PCE

The intermodulation spurious response attenuation of the receiver is the measure of its ability to receive a modulated input RF signal frequency in the presence of two unmodulated interfering signals so separated from the assigned input signal frequency and from each other that the n’ th order mixing of the two undesired signals can occur in the non-linear elements of the receiver, producing a third signal whose frequency is equal to that of the assigned input RF signal frequency. 1, record 3, English, - intermodulation%20spurious%20response%20attenuation

L'atténuation de la réponse aux produits d'intermodulation du récepteur est la mesure de sa capacité à recevoir un signal d'entrée RF modulé en présence de deux signaux brouilleurs non modulés qui sont séparés de la fréquence assignée du signal d'entrée et entre eux de telle sorte que le mélange de ne ordre des deux signaux non désirés puisse se produire dans les éléments non linéaires du récepteur, produisant un troisième signal dont la fréquence est égale à la fréquence assignée du signal d'entrée RF. 1, record 3, French, - att%C3%A9nuation%20des%20r%C3%A9ponses%20aux%20produits%20d%27intermodulation%20parasites
