- RTCM SC-104 is a communication protocol for sending differential GPS (DGPS) to a GPS receiver from a secondary source like a radio receiver. The standard is named for the Special Committee 104 of the Radio Technical Commission for Maritime Services (RTCM) that created it.The format does not define the source of the messages and has been used with systems as varied as longwave marine radio, communications satellite broadcasts, and internet distribution. The first widely used version of the format was released in 1990 and was based on the 30-bit long packet used by the GPS satellites, known as a "frame". Each message started with standardized two-frame header and then one or more data frames following. The frames were designed to be similar to GPS to make integration in GPS receivers easier, but had the disadvantage of having low channel efficiency and limiting the number of messages that could be sent in a given time. A completely new message format was introduced in 2003 for version 3 of the standard which used a variable-length format to improve efficiency and increase the number of messages that could be sent, which was important for real-time GPS corrections. The new standard also greatly increased the number of possible message types. As part of the standards process, the naming of the standard was changed, and version 3.1 became RTCM Standard 10403.1. As of 20 May 2021, the latest version is 3.3, or 10403.3, with Amendments 1 and 2. RTCM SC-104 is not the only standard for DGPS; Trimble introduced the (CMRx) format for the same basic purpose and there are several other similar standards used for special purposes. Most of these have fallen into disuse with the introduction of 10403.1. (en)
- RTCM SC 104 — формат передачи корректирующей информации ГНСС. Был разработан специальным комитетом Радиотехнической комиссии по морским сервисам США (англ. Radio Technical Commission for Maritime Services). Формат является полностью открытым и состоит из множества сообщений, позволяющих передавать информацию как по существующим, так и развертываемым спутниковым системам. За время своего существования формат несколько раз обновлялся и дополнялся. (ru)
- RTCM SC-104是一种通信协议,用于从无线电接收器等辅助源向GPS 接收器发送差分 GPS (D-GPS)。该标准以创建它的海事无线电技术委员会(RTCM) 的特别委员会 SC104 命名。该格式没有限定D-GPS消息的来源。该通信协议如今已应用于各种系统,如长波海事广播、通信卫星广播和互联网分发。 该协议的第一个广泛使用的版本于 1990 年发布,它基于 GPS 卫星使用的 30 位长数据包,称为“帧”。每条消息都以标准化的长度为两个帧的头部开始,紧跟着一个或多个数据帧。这些帧的设计类似于 GPS,可以很容易地集成到 GPS 接收器中,但缺点是信道效率低,限制了在给定时间内可以发送的消息数量。2003 年,标准的第 3 版引入了一种全新的消息格式,它使用可变长度格式来提高效率,从而增加可以发送的消息数量——这对于实时 GPS 校正很重要。新标准还大大增加了可能的消息类型的数量。遵照标准流程,标准的命名发生了变化,3.1 版成为RTCM 标准 10403.1 。截至2021年5月20日 ,最新版本是 3.3 或 RTSM Standard 10403.3,修正 1 和 2。 RTCM SC-104并不是支持D-GPS 的唯一标准。例如,Trimble公司基于相同的目的引入了紧凑型测量记录(CMRx) 格式。但是,随着 10403.1 的推出,其中大部分的协议被RTCM 10403.1所取代。 (zh)
