Complementary recording method and system for missing data of Beidou short message

The invention relates to a Beidou short message missing data additional recording method and system. The method comprises the following steps: establishing a deep extreme learning machine model; training the deep extreme learning machine model according to a pre-stored Beidou short message training set; acquiring a Beidou short message of missing data; and taking the Beidou short message of the missing data as the input of the trained deep extreme learning machine model to obtain a complementary message. It can be understood that according to the technical scheme provided by the invention, the complementary message can be obtained through the trained deep extreme learning machine model only by obtaining the Beidou short message of the missing data for one time, and the data transmission efficiency and the real-time performance are greatly improved. 本发明涉及一种北斗短报文缺失数据补录方法及系统，该方法包括：建立深度极限学习机模型；根据预先存储的北斗短报文训练集，对所述深度极限学习机模型进行训练；获取缺失数据的北斗短报文；将所述缺失数据的北斗短报文作为训练后的深度极限学习机模型的输入，得到补齐报文。可以理解的是，本发明提供的技术方案，仅需获取一次缺失数据的北斗短报文，便
