Every figure on this site is meant to be traceable to a source. This page sets out where those figures come from and how they are checked before anything is published, and it is the same person doing that checking on every page, me, Sebastian Holt.
1. Where the information comes from
The starting point is always the primary source, a provider’s own technical documentation, data sheets and licensing terms. Around that sit agency and standards bodies, the operators of public missions like Sentinel and Landsat, and the marketplaces that publish real price lists. Marketing copy is treated as background, not as evidence.
2. How the numbers are checked
Before a page goes live, every specification and price on it is checked back against that source. When two credible sources disagree, the page says which is which rather than quietly settling on one. Nothing is carried across from a competitor’s summary without returning to the original.
3. When something is not public
A gap is named as a gap, never filled with a guess dressed up as a fact.
A lot of what buyers want to know is simply not published, exact pricing, a precise revisit, a licensing edge case. When that happens the page says the figure is not public, or gives the range the source will support. A gap is named as a gap, never filled with a guess dressed up as a fact.
Here is what that looks like in practice, from the Unseen Labs review:
“Specific RF frequency bands intercepted are not disclosed on the site. The technology is described as multiband with no further band specification published.”
4. How a provider reaches a shortlist
The buyer’s guides rank providers for a specific job, and a provider earns its spot by fitting that job, the right sensor, the resolution it calls for, workable licensing, and data you can actually get. Relevance to the question sets the order, which is why the same company can lead one guide and go unmentioned in another.
5. Keeping pages current
Specifications and prices drift, and a review is only as good as its last check. Pages are revised when the underlying facts move, and the modified date carried in each page’s structured data marks when that last happened.
Found an error?
If a figure here is wrong or has aged out, I want to hear about it. Send the detail through the contact form and I will check it against the source and correct the page. Corrections are the fastest way this site gets better.
