[🔗](https://github.com/neilberkman/sidereon-ex/blob/main/lib/sidereon/gnss/fusion.ex#L178)

Carrier-phase range row with a caller-supplied float ambiguity.

# `t`

```elixir
@type t() :: %Sidereon.GNSS.Fusion.TightCarrierPhaseObservation{
  float_ambiguity_m: number(),
  phase_range_m: number(),
  sigma_m: number()
}
```

# `new`

```elixir
@spec new(number(), number(), number()) :: t()
```
