PSINS中的AVP

PSINS工具箱里面的trj.avp、trj.avp0等中的avp指的是姿態（attitude）、速度（velocity）和位置（position），最后加一個時間戳t：
avp=[att; vn; pos; t]。

姿態

姿態的構成為：俯仰角pitch+橫滾角roll+偏航角yaw。單位為弧度

速度

速度的構成為：東向速度+北向速度+天向速度。單位為m/s

位置

位置的構成為：緯度+經度+高度。其中緯度和經度的單位均為度，高度的單位為m

附：工具箱自帶的解釋

function avp = avpset(att, vn, pos, isdeg)
% avp=[attitude; velocity; position] setting.
%
% Prototype: avp = avpset(att, vn, pos)
% Inputs: att - attitude in deg
%        vn - velocity in m/s
%        pos - postion=[lat;lon;height] with lat and lon in deg,
%              while heigth in m. see posset.
%        isdeg - unit deg flag
% Output: avp=[attitude; velocity; position]

function avperr = avperrset(phi, dvn, dpos)
% avp errors setting.
%
% Prototype: avperr = avperrset(phi, dvn, dpos)
% Inputs: phi - platform misalignment angles. all in arcmin
%         dvn - velocity errors in m/s
%         dpos - position errors dpos=[dlat;dlon;dhgt], all in m
% Output: avperr = [phi; dvn; dpos]
