🔢 Actually resolve integers

Currently LEOGPS estimates float ambiguities only (no fixing) and does not exploit carrier phase information to do it. It only does pseudorange double differencing. If carrier phase is exploited we...

⚙ Numerical accuracies in orbit propagation via RK4 for the two-body case.

Related case to using RK4 or ODE45 for the J2-inclusive numerical propagator (one full day duration). ![image](https://user-images.githubusercontent.com/17903127/126344470-96e26591-8828-4d7f-a694-b1f36addc511.png) RK4 propagator using J2 and two-body produces about 1-km error as compared the...

⚙ Numerical accuracies in orbit propagation via RK4 for the two-body case.

> > > Hi, would it be right to say that the main contributor to the errors we see above is because the STK's J2 propagator uses secular rates of...
