that/which　
解析：1．考查非谓语动词。“spend… in ding… ”为固定结构，表示“花费金钱/精力等做某事”。故填explring。2．考查动词的时态和语态。空处在句中作谓语，结合时间状语Nw以及语境可知，此处表示现在正在进行的动作，故用现在进行时；satellites为复数形式，与rbit之间为主谓关系，故填are rbiting。3．考查形容词。空处作定语修饰recmmendatins and advice，故填形容词useful。
4．考查介词。as a result为固定搭配，表示“因此”，故填As。5．考查非谓语动词。in an/ne’s effrt t d sth. 为固定短语，故填 t grw。6．考查名词的数。requirement在此表示“必要条件，必备的条件”，是可数名词，且根据语境可知，此处应用复数形式，故填 requirements。7．考查连词。由语境可知，smartphne cameras与前面的GPS，memry fam pillws为并列关系，故填and。
