  Many modern and most future accelerators rely on precise configuration of
lattice and trajectory. The Integrable Optics Test Accelerator (IOTA) at
Fermilab that is coming to final stages of construction will be used to test
advanced approaches of control over particles dynamics. Various experiments
planned at IOTA require high flexibility of lattice configuration as well as
high precision of lattice and closed orbit control. Dense element placement
does not allow to have ideal configuration of diagnostics and correctors for
all planned experiments. To overcome this limitations advanced method of
lattice analysis is proposed that can also be beneficial for other machines.
Developed algorithm is based on LOCO approach, extended with various sets of
other experimental data, such as dispersion, BPM-to-BPM phase advances, beam
shape information from synchrotron light monitors, responses of closed orbit
bumps to variations of focusing elements and other. Extensive modeling of
corrections for a big number of random seed errors is used to illustrate
benefits from developed approach.
