A working service needs practiced people
Kenya Space Agency’s report on the 2025 regional Earth-observation centre training describes 24 participants and a programme combining system explanation, operational validation and supervised practice. It identifies facilities in Malindi and Nairobi. These are reported activities and aims; attendance totals alone do not establish that every participant can independently recover every failure.
For an invented handover, define tasks the receiving team must demonstrate: schedule a valid contact, recognise an invalid product, restore a failed component, and explain the resulting logs. Training becomes useful operational evidence when a person can perform the required task under representative conditions.

Find the dependency hidden behind the antenna
A station can lose useful service through a failed power supply, overheating electronics, a network outage or an unavailable qualified operator. Some failures can be handled through redundancy or maintenance procedures; the response depends on the actual design. A second dish does not necessarily protect a service if both dishes depend on the same failed power source.
In an invented exercise, five of six handover tasks pass, but the mandatory recovery task fails. Reporting an 83 percent completion score is arithmetically reasonable after rounding, yet it does not justify accepting the service. Mandatory requirements must be satisfied individually; a high average cannot cancel a critical failure.
Find the shared dependency
Original teaching diagram. Original dependency example; the real design requires its own configuration and recovery tests.

Cooling units, a container and site works illustrate the supporting infrastructure around a tracking terminal. A photograph alone does not establish internal equipment or operational readiness. Complete frame retained; technical resizing and format conversion only.
Look closely
Why might the equipment around an antenna matter to the service?
See what to notice
Cooling and housed electronics are examples of supporting infrastructure. The photograph shows external equipment and site works; actual readiness and redundancy require separate records and tests.

Leave the next shift enough to continue
A usable shift handover records the configuration, completed contacts, outstanding problems, next scheduled work and the owner of each unresolved action. Keep versions and times attached. A summary such as everything looks fine is not enough when the next operator must explain a missed contact or restore a particular setup.
For an invented rota, assume two people can perform a required recovery and one is absent. A schedule that needs two qualified people simultaneously now lacks coverage even if many other staff are available. Evaluate the capability the task needs, not simply the building’s headcount. Ground infrastructure is sustained through both equipment and demonstrated human capability.
