| #### バージョンの使い分け | ||
| - Version 1 | ||
| - 主に，Telemetry ID で区別される，パケットごとに構造化され定義されたテレメトリ (Character Tlm Packet) に使う | ||
| - C2A では，Tlm Cmd DB の Tlm DB によってスキーマが定義され，時系列データベースなどに格納されることが一般的である | ||
| - 基本的にはパケット分割されない（Sequence Flag が Standalone Packet である） | ||
| - Version 2 | ||
| - 主に，画像などのミッションデータやメモリダンプ (Binary Tlm Packet) を送信するときに使う | ||
| - パケット分割は許容される |

| ##### Version 2 | ||
| - On-Board Subnetwork Time （将来拡張） | ||
| - 各ボードで作られたパケットの時刻を統一的に管理するために，オンボードサブネットワークで共通の時刻体系に基づくテレメトリ生成時刻 | ||
| - `0xFFFFFFFF` の場合， パケット中継中に MOBC (地上局とつながる OBC) で，上書き設定される | ||
| - On-Board Subnetwork Time を取得できない機器向け |

There was a problem hiding this comment.
つまり，
- ver1, ver2 で offset が異なってしまっても良いのか
- そもそもこれ必要か？

補足
これまでのパケット（tlm db で定義される，構造化されたテレメ）と，ミッションデータのテレメ，それぞれを区別する名前がほしい．．．．
前者を Character tlm packet，後者を Binary tlm packet，とか？ @sksat @KOBA789 @ToshiAki64 @chutaro どう思います？
