据1989年3月18日英国《国际飞行》报道,巴基斯坦声称它将于今年底发射自行研制的“巴达尔-A”(Badar)卫星。该卫星星体是个26面的多面球体,重70公斤,主要功能是贮存和传输数字信息,象一个轨道邮箱。卫星将进入600公里近极地轨道,倾角95～98度,运行周期100分钟,每天飞越巴基斯坦3～4次,每次15～20分钟。 According to a report on “International Flight” dated March 18, 1989, Pakistan claims that it will launch its own self-developed “Badar” satellite by the end of this year. The satellite is a 26-sided multi-faceted ball, weighing 70 kg, the main function is to store and transmit digital information, like a track mailbox. The satellite will enter the 600-kilometer near polar orbit at an inclination of 95-98 degrees for 100 minutes and overfly Pakistan 3 to 4 times a day for 15 to 20 minutes each.
